Switch all 14 Lance crate dependencies from lance-format/lance (v5.0.0-beta.5)
to theDeltaLab/lance (branch main) to track our fork which will contain the
upstream bitmap fix for stale vector indices after compaction.
Add a defensive fallback in VectorQuery: when a query fails due to stale
fragment references in the index ("specified fragment id X does not exist"),
automatically retry with use_index=false (flat search) and log a warning.
This prevents query failures while the root cause (fragment_bitmap
inconsistency in Lance's optimize_indices merge path) is being fixed upstream.
See: TheDeltaLab/lance#3

Remove the stale index query fallback (is_stale_index_error + flat search retry) — the Lance fork itself will contain the proper fix. Also fix the GitHub org casing from theDeltaLab to TheDeltaLab. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
lance-format/lance(v5.0.0-beta.5) toTheDeltaLab/lance(branch main) to track our forkContext
Lance's vector index can contain stale ROW_ID references after compaction, causing query failures. The root cause is tracked in TheDeltaLab/lance#3 and will be fixed in the fork.
