docs(python): fix cross-references that resolved to the wrong page

`mkdocs build --strict` only catches references it cannot resolve. A bare anchor such as `[limit][]` or `[vector search][search]` is matched by autorefs against any heading on the site, so six of them silently linked into the JavaScript reference instead. The relative links in `permutation.py` and `remote/errors.py` pointed at in-page anchors and paths that do not exist. Targets that still exist here or in an imported inventory now use mkdocstrings references; the guide pages deleted in #2770 use their lancedb.com URLs. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
docs: clear the mkdocs warning backlog so --strict passes

-* Use repository-defined Cargo profiles instead of ad hoc LTO overrides.
-* Use `release-with-debug` for benchmarks and profiling so optimized builds keep debug symbols without a rebuild.
-* Use `release-no-lto` only for local debugging, IO-bound benchmarks, or compile-time-sensitive performance investigation where LTO would not affect the measured bottleneck.

-
-#### Parameters
-
-* **distributedMetrics?**: [`AnalyzePlanDistributedMetrics`](../type-aliases/AnalyzePlanDistributedMetrics.md)

-
-### select()
-
-```ts
-select(columns): this
-```
-
-Return only the specified columns.
-
-By default a query will return all columns from the table.  However, this can have
-a very significant impact on latency.  LanceDb stores data in a columnar fashion.  This
-means we can finely tune our I/O to select exactly the columns we need.
-
-As a best practice you should always limit queries to the columns that you need.  If you
-pass in an array of column names then only those columns will be returned.
-
-You can also use this method to create new "dynamic" columns based on your existing columns.
-For example, you may not care about "a" or "b" but instead simply want "a + b".  This is often
-seen in the SELECT clause of an SQL query (e.g. `SELECT a+b FROM my_table`).
-
-To create dynamic columns you can pass in a Map<string, string>.  A column will be returned
-for each entry in the map.  The key provides the name of the column.  The value is
-an SQL string used to specify how the column is calculated.
-
-For example, an SQL query might state `SELECT a + b AS combined, c`.  The equivalent
-input to this method would be:
-
-#### Parameters
-
-* **columns**: `string` \| `string`[] \| `Record`&lt;`string`, `string`&gt; \| `Map`&lt;`string`, `string`&gt;
-
-#### Returns
-
-`this`
-
-#### Example
-
-```ts
-new Map([["combined", "a + b"], ["c", "c"]])
-
-Columns will always be returned in the order given, even if that order is different than
-the order used when adding the data.
-
-Note that you can pass in a `Record<string, string>` (e.g. an object literal). This method
-uses `Object.entries` which should preserve the insertion order of the object.  However,
-object insertion order is easy to get wrong and `Map` is more foolproof.

-### useLsm()
-
-```ts
-useLsm(enable): this
-```
-
-Control MemWAL read routing for this query.
-
-By default (unset), when the table carries a MemWAL write spec (see
-[Table#setLsmWriteSpec](Table.md#setlsmwritespec)), reads are routed through the LSM scanner so
-they also return data written via the `mergeInsert` LSM path that has not yet
-been compacted into the base table (the active/frozen in-memory memtables and
-the flushed generations), deduplicated by primary key; a table without a spec
-reads the base table.
-
-#### Parameters
-
-* **enable**: `boolean`
-    `true` forces the LSM scanner and errors if the table has no
-    MemWAL write spec. `false` bypasses the MemWAL and reads the base table only,
-    even when a spec is present.
-    Note: the LSM scanner does not support every query shape (e.g. reranking,
-    hybrid search, `orderBy`). On a MemWAL table those shapes error unless
-    `useLsm(false)` is set, because a base-only read would silently exclude
-    un-compacted MemWAL data.

-The filter should be supplied as an SQL query string.  For example:
-
-#### Parameters
-
-* **predicate**: `string`
-
-#### Returns
-
-`this`
-
-#### Example
-
-```ts
-x > 10
-y > 0 AND y < 100
-x > 5 OR y = 'test'
-
-Filtering performance can often be improved by creating a scalar index
-on the filter column(s).
-
-Calling this multiple times combines the filters with a logical AND rather
-than replacing the previous filter.

-Request cancellation of a server-side job by id.

-Resolves to true if the server accepted the cancellation, false if no

-
-Define a materialized view named `name` over the table `source`.
-
-The view is created empty, with the query recorded in its schema
-metadata; `view.refresh()` computes the rows. The view is a normal
-table: it can be queried, indexed and searched, and it appears in
-`tableNames`. The source table must have stable row ids (create it with
-the `newTableEnableStableRowIds` storage option); they keep the view's
-provenance valid across source compactions and cannot be enabled after
-a table exists. Local databases only.

Will Jones	011def461c	docs(python): fix cross-references that resolved to the wrong page `mkdocs build --strict` only catches references it cannot resolve. A bare anchor such as `[limit][]` or `[vector search][search]` is matched by autorefs against any heading on the site, so six of them silently linked into the JavaScript reference instead. The relative links in `permutation.py` and `remote/errors.py` pointed at in-page anchors and paths that do not exist. Targets that still exist here or in an imported inventory now use mkdocstrings references; the guide pages deleted in #2770 use their lancedb.com URLs.

Will Jones	ed6be12ad6	docs: clear the mkdocs warning backlog so --strict passes `mkdocs build` emitted 61 warnings on main, and rendering the previously undocumented classes in this PR pushed that to 158. That backlog is what blocks turning on strict mode (#3707), so clear it here rather than leave it worse than we found it. Most of it was one systematic false positive: griffe cannot see the generated `__init__` of a pydantic dataclass, so every documented parameter looked unknown. `warn_unknown_params` turns that check off. The rest were real docstring bugs, in 15 docstrings: * Prose trailing a `Parameters` section is read as parameter names, which invented parameters called `The`, `you` and `To`. Moved into `Notes` or the summary. * numpydoc only reads a type when the colon has spaces around it. Where the documented name is a pydantic attribute rather than a signature parameter, griffe has no signature to fall back on and the type was dropped. Affects nine embedding classes. * `num_partitions, default sqrt(num_rows)` and friends parse as a list of names, rendering a bogus `default` parameter. * One parameter indented five spaces instead of four. `nodejs/CONTRIBUTING.md` links to the repo-root CONTRIBUTING.md, which does not resolve once typedoc copies the file into `docs/src/js/_media/`; an absolute URL works from both places. `mkdocs build --strict` now exits 0.

Will Jones	ac2b689cdb	docs(python): render index/embeddings/remote/rerankers from __all__ Four packages are now rendered by a single mkdocstrings directive each, driven by the module's `__all__`, instead of a hand-maintained list of symbols. These were where most of the drift was: 7 of 12 rerankers and 14 of 17 embedding functions had never been listed. `lancedb.embeddings` had no `__all__`; without one mkdocstrings renders no members at all for a re-export package, so one is added. AGENTS.md gains a section describing how the reference page is wired up and how to check a docs build locally, plus a step in the "adding a new method on Table" checklist.

Will Jones	4fc8114871	docs(python): add missing public APIs to the Python reference The Python API reference page had drifted from the public API. Branch management (`Branches` / `AsyncBranches`, which own `diff` and `merge`), structured full-text query classes, take queries, blob helpers, namespace connections, most rerankers and embedding functions, the PyTorch dataloader, and several other public symbols were never listed, so they did not appear in the rendered docs. Also fixes docstring cross-references that pointed at guide pages which have since moved off this site, and at unresolvable relative targets (`[Table](Table)`, `[PyArrow Table](pyarrow.Table)`).
