ci: fix pypi publish on mac/windows/arm (#3449)

The python-v0.32.0 publish run failed on every build matrix entry. Three
independent issues:

1. **Mac and Windows**: `pypa/gh-action-pypi-publish` only runs on
Linux, but was being called inline from each build job.
2. **Linux (all arches)**: `pypa/gh-action-pypi-publish` derives its
docker image name from `github.action_repository`, which is empty when
the action is invoked from inside a composite action
(actions/runner#2473 — pypa's own `action.yml` references this bug). It
falls back to `github.repository`, generating
`docker://ghcr.io/lancedb/lancedb:<tag>`, which doesn't exist →
`denied`. Only the ARM matrix entry surfaced this because it failed
first and cancel-cascaded the rest.
3. **Windows**: `upload-artifact` in `build_windows_wheel` pointed at
`python\target\wheels`, but maturin writes to the workspace-root
`target/wheels`. The artifact was always empty. Also, `pypi-publish.yml`
passed a `vcpkg_token` input that the composite doesn't declare.

## Changes

- Build jobs (linux/mac/windows) now upload their wheels as
`actions/upload-artifact` artifacts.
- New Linux `publish` job downloads all wheel artifacts and runs the
Fury or PyPA publish step directly (not via a composite), so
`github.action_repository` resolves correctly.
- Delete the unused `upload_wheel` composite action.
- Drop the broken upload-artifact step inside `build_windows_wheel`.
- Remove the bogus `vcpkg_token` input.
- Fury upload now loops over all wheels instead of just the first.
- Bump `actions/checkout`, `actions/upload-artifact`,
`actions/download-artifact` to current major versions (Node 24) to clear
deprecation warnings.
- Bump Windows job timeout 60 → 90 minutes; previous run was
cancel-timing-out on a 60m cap.
- Use `rust-lld` as the Windows MSVC linker via
`CARGO_TARGET_X86_64_PC_WINDOWS_MSVC_LINKER`. `link.exe` is
single-threaded and the long pole on Windows builds.

Fixes #3445

## Test plan

- [x] Open this PR — `paths` filter triggers a dry-run build on all
three platforms.
- [x] Verify all three builds produce wheels.
- [x] Confirm the `pypa/gh-action-pypi-publish` container actually
starts (the actions/runner#2473 bug) via the `publish-dry-run` job
pointed at TestPyPI.
- [x] **REMOVE BEFORE MERGE**: drop the `publish-dry-run` job and the
now-redundant `actions/upload-artifact` runs on PRs (currently always-on
so the dry-run has wheels to publish).
- [ ] After merge, cherry-pick onto `python-v0.32.0` and force-push the
tag to re-trigger the publish.

-name: lancedb-update-lance-dependency
-description: Update LanceDB to a specific Lance release or tag. Use when bumping Lance dependencies in the lancedb repository, including Rust workspace Lance crates, Java lance-core, validation, branch creation, commit, push, and PR creation when requested.
----
-
-# LanceDB Update Lance Dependency
-
-## Scope
-
-Use this skill in the `lancedb/lancedb` repository when updating the Lance dependency to a specific Lance version or tag.
-
-Inputs can be a version (`7.2.0-beta.1`), a tag (`v7.2.0-beta.1`), a tag ref (`refs/tags/v7.2.0-beta.1`), or `latest`.
-
-## Workflow
-
-1. Confirm the worktree status with `git status --short`.
-2. Resolve the target Lance version:
-
-   - If the input is `latest`, empty, or omitted, run:
-
-     ```bash
-     python3 ci/check_lance_release.py
-     ```
-
-     Parse the JSON output. If `needs_update` is not `true`, stop without creating a PR. Otherwise use `latest_tag`.
-
-   - If the input is explicit, use it directly.
-
-3. Compute update metadata without changing files:
-
-   ```bash
-   python3 ci/update_lance_dependency.py "$TAG_OR_VERSION" --metadata-only
-   ```
-
-   Before making changes, check for an existing open PR with the emitted `pr_title`:
-
-   ```bash
-   gh pr list --search "\"$PR_TITLE\" in:title" --state open --limit 1 --json number,url,title
-   ```
-
-   If a matching open PR exists, stop and report it instead of creating a duplicate.
-
-4. Run the deterministic update entrypoint:
-
-   ```bash
-   python3 ci/update_lance_dependency.py "$TAG_OR_VERSION"
-   ```
-
-   This updates the Rust workspace Lance dependencies through `ci/set_lance_version.py`, updates `java/pom.xml`, refreshes Cargo metadata, and prints JSON metadata containing `branch_name`, `commit_message`, and `pr_title`.
-
-5. Run validation:
-
-   ```bash
-   cargo clippy --quiet --workspace --tests --all-features -- -D warnings
-   cargo fmt --all --quiet
-   ```
-
-   Fix real diagnostics and rerun clippy until it succeeds. Do not skip warnings.
-
-6. Inspect `git status --short` and `git diff` to ensure only the Lance dependency update and required compatibility fixes are present.
-
-7. If the task only asks to prepare local changes, stop here and report the changed files and validation result.
-
-8. If the task asks to publish the update, create a branch using the printed `branch_name`, stage all relevant files, and commit using the printed `commit_message`. Do not amend or rewrite existing commits.
-
-9. Push to `origin`. Before creating the PR, check that the current token has push permission:
-
-   ```bash
-   gh api repos/lancedb/lancedb --jq .permissions.push
-   ```
-
-   If the remote branch already exists for the same generated branch name, delete the remote ref with `gh api -X DELETE repos/lancedb/lancedb/git/refs/heads/$BRANCH_NAME`, then push. Do not force-push.
-
-10. Create a PR targeting `main` with the printed `pr_title`. If there is no PR template, keep the body to two or three concise sentences: state the Lance dependency bump, note any required compatibility fixes, and link the triggering Lance tag or release.
-
-11. Read back the remote PR title after creation. If it is not a Conventional Commit title, fix it immediately.
-
-12. When running in GitHub Actions after creating the LanceDB PR, trigger the Sophon dependency update:
-
-    ```bash
-    gh workflow run codex-bump-lancedb-lance.yml \
-      --repo lancedb/sophon \
-      -f lance_ref="$LANCE_TAG" \
-      -f lancedb_ref="$BRANCH_NAME"
-    gh run list --repo lancedb/sophon --workflow codex-bump-lancedb-lance.yml --limit 1 --json databaseId,url,displayTitle
-    ```
-
-    Use the emitted metadata `tag` value as `LANCE_TAG`. Do this only after a new LanceDB PR has been created. If the update was skipped because no update is needed or an open PR already exists, do not trigger Sophon.
-
-## GitHub Actions
-
-When this skill is used from GitHub Actions, `TAG`, `GH_TOKEN`, and `GITHUB_TOKEN` may already be set. Resolve `latest` first when `TAG` is empty. Once an explicit tag or version is known, use:
-
-```bash
-python3 ci/update_lance_dependency.py "$TAG" --github-output "$GITHUB_OUTPUT"
-```
-
-Then use the emitted `branch_name`, `commit_message`, and `pr_title` values for branch, commit, and PR creation.

+          You are running inside the lancedb repository on a GitHub Actions runner. Update the Lance dependency to version ${VERSION} and prepare a pull request for maintainers to review.
 
-          Use \$lancedb-update-lance-dependency with target "${TARGET_TAG}".
+          Follow these steps exactly:
+          1. Use script "ci/set_lance_version.py" to update Lance Rust dependencies. The script already refreshes Cargo metadata, so allow it to finish even if it takes time.
+          2. Update the Java lance-core dependency version in "java/pom.xml": change the "<lance-core.version>...</lance-core.version>" property to "${VERSION}".
+          3. Run "cargo clippy --workspace --tests --all-features -- -D warnings". If diagnostics appear, fix them yourself and rerun clippy until it exits cleanly. Do not skip any warnings.
+          4. After clippy succeeds, run "cargo fmt --all" to format the workspace.
+          5. Ensure the repository is clean except for intentional changes. Inspect "git status --short" and "git diff" to confirm the dependency update and any required fixes.
+          6. Create and switch to a new branch named "${BRANCH_NAME}" (replace any duplicated hyphens if necessary).
+          7. Stage all relevant files with "git add -A". Commit using the message "${COMMIT_TYPE}: update lance dependency to v${VERSION}".
+          8. Push the branch to origin. If the remote branch already exists, delete it first with "gh api -X DELETE repos/lancedb/lancedb/git/refs/heads/${BRANCH_NAME}" then push with "git push origin ${BRANCH_NAME}". Do NOT use "git push --force" or "git push -f".
+          9. env "GH_TOKEN" is available, use "gh" tools for github related operations like creating pull request.
+          10. Create a pull request targeting "main" with title "${COMMIT_TYPE}: update lance dependency to v${VERSION}". First, write the PR body to /tmp/pr-body.md using a heredoc (cat <<'EOF' > /tmp/pr-body.md). The body should summarize the dependency bump, clippy/fmt verification, and link the triggering tag (${TAG}). Then run "gh pr create --body-file /tmp/pr-body.md".
+          11. After creating the PR, display the PR URL, "git status --short", and a concise summary of the commands run and their results.
 
           Constraints:
-          - Use env "GH_TOKEN" for GitHub operations.
+          - Use bash commands; avoid modifying GitHub workflow files other than through the scripted task above.
-          - Do not merge the pull request.
+          - Do not merge the PR.
-          - Do not force-push.
+          - If any command fails, diagnose and fix the issue instead of aborting.
-          - Do not create a duplicate pull request if an open PR already exists for the target Lance version.
-          - If any command fails, diagnose and fix the root cause instead of aborting.

-# Class: Scannable
-
-A data source that can be scanned as a stream of Arrow `RecordBatch`es.
-
-`Scannable` wraps the schema + optional row count + rescannable flag and
-a callback that yields batches one at a time. It is passed to consumers
-(e.g. `Table.add`, `createTable`, `mergeInsert` — follow-up work) that
-need to pull data without materializing the full dataset in JS memory.
-
-Batches cross the JS↔Rust boundary as Arrow IPC Stream messages; a fresh
-writer serializes each batch, and the Rust side decodes it with
-`arrow_ipc::reader::StreamReader`. One batch is in flight at a time.
-
-## Properties

-
-## Methods
-
-### fromFactory()
-
-```ts
-static fromFactory(
-   schema,
-   factory,
-   opts): Promise<Scannable>
-```
-
-Build a Scannable from an explicit schema and a factory that returns a
-fresh batch iterator on each call.
-
-The factory is invoked once per scan. Each iterator yields
-`RecordBatch`es matching the declared schema. Use this when you need
-direct control over the pull loop — for example, to wrap a streaming
-source whose batches are produced lazily.
-
-#### Parameters
-
-* **schema**: `Schema`&lt;`any`&gt;
-    The Arrow schema of the produced batches.
-
-* **factory**
-    Called at the start of each scan to produce a batch
-    iterator. Must be idempotent when `rescannable` is true.
-
-* **opts**: [`ScannableOptions`](../interfaces/ScannableOptions.md) = `{}`
-    Optional hints. `rescannable` defaults to `true`; set to
-    `false` if calling `factory()` twice would not reproduce the same data.
-
-#### Returns
-
-`Promise`&lt;[`Scannable`](Scannable.md)&gt;
-
-***
-
-### fromIterable()
-
-```ts
-static fromIterable(
-   schema,
-   iter,
-   opts): Promise<Scannable>
-```
-
-Build a Scannable from an iterable of `RecordBatch`es. `rescannable`
-defaults to `false`. Pass an explicit schema so the consumer can
-validate before any batch is pulled.
-
-`opts.rescannable: true` is honest for replayable iterables (Arrays,
-Sets, or custom iterables whose `[Symbol.iterator]()` returns a fresh
-iterator each call). It is rejected for one-shot iterables (generators,
-async generators, or already-an-iterator inputs) because their
-`[Symbol.iterator]()` returns the same exhausted object on the second
-scan. For replayable sources outside this shape, use
-`fromFactory(schema, () => createIter(), { rescannable: true })`.
-
-Note: when `opts.rescannable` is `true`, the constructor calls
-`[Symbol.iterator]()` once on the input to perform the structural check.
-
-#### Parameters
-
-* **schema**: `Schema`&lt;`any`&gt;
-
-* **iter**: `Iterable`&lt;`RecordBatch`&lt;`any`&gt;&gt; \| `AsyncIterable`&lt;`RecordBatch`&lt;`any`&gt;&gt;
-
-* **opts**: [`ScannableOptions`](../interfaces/ScannableOptions.md) = `{}`

-***
-
-### fromRecordBatchReader()
-
-```ts
-static fromRecordBatchReader(reader, opts): Promise<Scannable>
-```
-
-Build a Scannable from an Arrow `RecordBatchReader`. A reader can only
-be consumed once; `rescannable` defaults to `false`.
-
-The reader must already be opened (via `.open()`) so its `.schema` is
-populated. `RecordBatchReader.from(...)` returns an unopened reader.
-
-`opts.rescannable: true` is rejected because `RecordBatchReader` is a
-self-iterator (its `[Symbol.iterator]()` returns itself), and this
-constructor does not call `reader.reset()` between scans, so a second
-scan would always see an exhausted reader. For genuinely replayable
-sources, use
-`fromFactory(schema, () => openReader(), { rescannable: true })`,
-which mints a fresh reader on each scan.
-
-#### Parameters
-
-* **reader**: `RecordBatchReader`&lt;`any`&gt;
-
-* **opts**: [`ScannableOptions`](../interfaces/ScannableOptions.md) = `{}`
-
-#### Returns

-
-***
-
-### fromTable()
-
-```ts
-static fromTable(table, opts): Promise<Scannable>
-```
-
-Build a Scannable from an in-memory Arrow `Table`. Always rescannable;
-the table's batches are replayed on each scan.
-
-The table's row count is authoritative: `opts.numRows` must either be
-omitted or equal to `table.numRows`. `opts.rescannable` of `false` is
-rejected because in-memory Tables are always rescannable.
-
-#### Parameters
-
-* **table**: `Table`&lt;`any`&gt;

-* **opts**: [`ScannableOptions`](../interfaces/ScannableOptions.md) = `{}`

-Install an [LsmWriteSpec](../interfaces/LsmWriteSpec.md) on this table, selecting Lance's MemWAL

-
-`LsmWriteSpec` chooses one of three sharding strategies via `specType`:
-
-- `"bucket"` — hash-bucket writes by the single-column unenforced primary
-  key (`column` and `numBuckets` required).
-- `"identity"` — shard by the raw value of a scalar `column`.
-- `"unsharded"` — route every write to a single shard.
-
-All variants require the table to have an unenforced primary key
-([Table#setUnenforcedPrimaryKey](Table.md#setunenforcedprimarykey)); bucket sharding additionally
-requires it to be the single column being bucketed.
