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

return version info for all write operations (add, update, merge_insert
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.
