LuQQiu ed594b0f76 feat: return version for all write operations (#2368)

and column modification operations)

<!-- This is an auto-generated comment: release notes by coderabbit.ai

## Summary by CodeRabbit

- **New Features**
- Table modification operations (add, update, delete, merge,
add/alter/drop columns) now return detailed result objects including
version numbers and operation statistics.
- Result objects provide clearer feedback such as rows affected and new
table version after each operation.

- **Documentation**
- Updated documentation to describe new result objects and their fields
for all relevant table operations.
- Added documentation for new result interfaces and updated method
return types in Node.js and Python APIs.

- **Tests**
- Enhanced test coverage to assert correctness of returned versioning
and operation metadata after table modifications.

A Python library for LanceDB.

Installation

pip install lancedb

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

Usage

Basic Example

import lancedb
db = lancedb.connect('<PATH_TO_LANCEDB_DATASET>')

results = table.search([0.1, 0.3]).limit(20).to_list()
print(results)
