feat: add convenience API for bulk ingest

[kentkwu]

This PR adds a higher-level API for bulk ingest on AdbcConnection, wrapping the low-level statement option + bind + execute_update pattern.

await conn.ingest('my_table', data)
await conn.ingest('my_table', data, { mode: IngestMode.Append })
await conn.ingest('my_table', data, { mode: IngestMode.Replace, dbSchema: 'public' })

Also fixes the underlying bind() implementation to use AdbcStatementBindStream instead of AdbcStatementBind, removing the previous single-batch limitation. bind() now accepts Tables with any number of batches.

Changes

• AdbcConnection.ingest(tableName, data, options?) convenience method
• IngestMode and IngestOptions exported types
• AdbcStatement.bind() now accepts Table only (was RecordBatch | Table)
• AdbcStatement.bind() upgraded to use AdbcStatementBindStream in the Rust layer, removing the single-batch limitation
