fix(ci): allow recovery artifact downloads

## Summary

`opendal 0.58.1` (the version pulled in transitively via Lance) already
ships
`goosefs-sdk 0.1.9`, which includes the upstream fix for the 0.1.6
compile
break. The explicit version pin that lancedb has been carrying since the
GooseFS feature was introduced is therefore no longer necessary and is
now
redundant work to maintain.

## Changes

- Remove the direct `goosefs-sdk` dependency from
`rust/lancedb/Cargo.toml`
(it was pinned to `=0.1.9` with a comment referencing the 0.1.6 compile
  break).
- Remove the `dep:goosefs-sdk` entry from the `goosefs` cargo feature,
since
  no source file in lancedb imports the crate directly.
- Refresh `Cargo.lock`; `goosefs-sdk 0.1.9` now resolves transitively
through
  `lance` → `opendal 0.58.1`.

## Verification

- `cargo fmt --all` — clean
- `cargo check --features remote,goosefs --tests --examples` — passes
- `Cargo.lock` confirms `goosefs-sdk 0.1.9` is still resolved (now
transitively), so the `goosefs` feature continues to enable the same set
of
  Lance/IOPaths as before.

## Backwards compatibility

No public API changes. The `goosefs` cargo feature still activates
`lance/goosefs`, `lance-io/goosefs`, and
`lance-namespace-impls/dir-goosefs`,
and the same `goosefs-sdk 0.1.9` version is selected by the resolver.

+## Python API reference
+
+`docs/src/python/python.md` is the entire Python API reference. It is maintained by
+hand, and anything not listed there is not rendered at all, so new public classes and
+module-level functions have to be added explicitly. How depends on the module:
+
+* `lancedb.index`, `lancedb.embeddings`, `lancedb.remote`, and `lancedb.rerankers` are
+  rendered by a single directive each, driven by the module's `__all__`. Add the new
+  name to `__all__` and it appears; forget, and it is silently omitted.
+* Everything else (`lancedb`, `lancedb.table`, `lancedb.query`, `lancedb.db`, ...) is
+  listed symbol by symbol. Add a `::: lancedb.<module>.<Name>` line to the matching
+  section, and remember that the page separates synchronous and asynchronous APIs.
+
+Deliberately undocumented: concrete implementations reached through an abstract base
+(`LanceTable`, `LanceDBConnection`, `RemoteDBConnection`), query base classes already
+covered by `inherited_members`, and internal helpers.
+
+Cross-references in docstrings use mkdocstrings syntax, `[text][lancedb.table.Table]`.
+Plain relative links such as `[Table](Table)` do not resolve. To check your work:
+
+```shell
+pip install -r docs/requirements.txt
+cd docs && PYTHONPATH=. mkdocs build
+```
+
+The docs site only builds on pushes to `main`, so this is not covered by PR CI.

+
+The handle is constructed without a server round trip; an unknown id
