chore: update lance dependency to v1.0.0-beta.4

feat(python): support to_pydantic in async (#2438 )
This request improves support for `pydantic` integration by adding `to_pydantic` method to asynchronous queries and handling models that use `alias` in field definitions. Fixes #2436 and closes #2437 .  ## Summary by CodeRabbit - **New Features** - Added support for converting asynchronous query results to Pydantic models. - **Bug Fixes** - Simplified conversion of query results to Pydantic models for improved reliability. - Improved handling of field aliases and computed fields when mapping query results to Pydantic models. - **Tests** - Added tests to verify correct mapping of aliased and computed fields in both synchronous and asynchronous scenarios.

lancedb automation	e7f0e2e81a	chore: update lance dependency to v1.0.0-beta.4	2025-11-19 19:59:12 +00:00
Mykola Skrynnyk	ca8d118f78	feat(python): support `to_pydantic` in async (#2438 ) This request improves support for `pydantic` integration by adding `to_pydantic` method to asynchronous queries and handling models that use `alias` in field definitions. Fixes #2436 and closes #2437 . <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - New Features - Added support for converting asynchronous query results to Pydantic models. - Bug Fixes - Simplified conversion of query results to Pydantic models for improved reliability. - Improved handling of field aliases and computed fields when mapping query results to Pydantic models. - Tests - Added tests to verify correct mapping of aliased and computed fields in both synchronous and asynchronous scenarios. <!-- end of auto-generated comment: release notes by coderabbit.ai -->	2025-11-19 11:20:14 -08:00
Wyatt Alt	386fc9e466	feat: add num_attempts to merge insert result (#2795 ) This pipes the num_attempts field from lance's merge insert result through lancedb. This allows callers of merge_insert to get a better idea of whether transaction conflicts are occurring.	2025-11-19 09:32:57 -08:00
