bug: binding docstrings say stable row ids do not survive an update

Description

WriteParams::enable_stable_row_ids (Rust), write_dataset and write_fragments (Python) and CommitBuilder.useStableRowIds (Java) all say the same thing: "These row ids are stable after compaction operations, but not after updates." The format spec says the opposite in docs/src/format/table/row_id_lineage.md: "When stable row IDs are enabled, updates preserve the logical row ID and remap it to a new physical address instead of assigning a new ID." So does the code, and so do the tests: test_row_id_stability_across_update_and_merge_insert asserts the id is unchanged after an update with the feature on, and assert_ne! with it off.

A user reading the docstring concludes they cannot store _rowid externally on a table that takes updates, which is the main thing the feature exists to allow.

Two more places carry a narrower version of the same claim: Dataset::migrate_to_stable_row_ids and Java's hasStableRowIds mention compaction only. A comment above unremappable_index_coverage in rust/lance/src/dataset/optimize.rs says "Stable row ids keep the addresses across a rewrite", which is backwards: a rewrite is what moves addresses. A test comment in rust/lance/src/dataset/rowids.rs says "Updated fragments get fresh row ids" directly above assertions proving that the id survives and no new id is minted.

Steps to reproduce

// The docstring on this field says the id will not survive the update below.
let write_params = WriteParams { enable_stable_row_ids: true, ..Default::default() };
// ... write, then read _rowid for a row, then update that row ...
// The id is unchanged: rust/lance/src/dataset/rowids.rs::test_row_ids_update

Expected behavior

The binding docs state what the spec, the code and the tests already agree on.

Lance version

13.0.0-beta.4 (main)

Language binding

Rust, Python, Java

Start with the docstrings for WriteParams::enable_stable_row_ids, write_dataset, write_fragments, CommitBuilder.useStableRowIds, Dataset::migrate_to_stable_row_ids, and Java's hasStableRowIds. Compare them with docs/src/format/table/row_id_lineage.md and the assertions in rust/lance/src/dataset/rowids.rs, including test_row_ids_update. Done means all binding docs and the noted comments consistently describe row IDs surviving updates while physical addresses may change.
