Google Team Member 9579bea05d feat(plugins): Add flush mechanism to BigQueryAgentAnalyticsPlugin 
This change introduces a `flush` method to the `BigQueryAgentAnalyticsPlugin`. This ensures that all pending log events are written to BigQuery before the agent's run completes.

Key changes:

- Added `flush()` method to `BigQueryAgentAnalyticsPlugin` to force write of pending events.
