feat(nodejs): add Connection.renameTable with namespace support (#3365)

### Summary

- Expose Connection.renameTable in the Node.js bindings and align it
with existing namespace-aware connection APIs.

### Changes

- Add napi-rs rename_table on Connection, delegating to Rust
Connection::rename_table.
- Add renameTable(oldName, newName, namespacePath?) on abstract
Connection and implement on LocalConnection.
- Add a connection test that renames a table and checks names / open
behavior.

#### Testing

- cd nodejs && npm run build
- cd nodejs && npm test __test__/connection.test.ts

fix : #3364
