Dialect Capabilities

Based on knex_dart_capabilities (bigquery dialect):

Known Limitations

• Each query is submitted as a separate BigQuery job.
• Large result pagination is not yet surfaced by this client (single result fetch path).
• Parameter type mapping is basic (BOOL, INT64, FLOAT64, STRING).
