### Summary Adds update_field_metadata to the client SDK (Rust core, Python, and TypeScript) so clients can edit per-field (column) Arrow metadata (schema.fields[].metadata) ### Testing - added unit tests - ran E2E against a local server on both local and remote tables (set → merge → delete), across Python sync/async and TypeScript ### Next steps - deprecate replace_field_metadata in the python lancedb favor of this (typescript didn't have replace_field_metadata method). This matches Lance's API direction (Lance already deprecated replace_field_metadata for update_field_metadata)

Preview Releases
Stable releases are created about every 2 weeks. For the latest features and bug fixes, you can install the preview release. These releases receive the same level of testing as stable releases, but are not guaranteed to be available for more than 6 months after they are released. Once your application is stable, we recommend switching to stable releases.
pip install --pre --extra-index-url https://pypi.fury.io/lancedb/ lancedb
