Extract Supervisor class to manage the worker pool lifecycle: task claiming, queue feeding, batch mode, max-tasks tracking, and graceful/forced shutdown. Worker is simplified to only consume tasks from a shared asyncio.Queue. The Supervisor issues a single SELECT FOR UPDATE SKIP LOCKED per poll cycle to claim up to `concurrency` tasks at once, reducing database load compared to each worker querying the DB independently. Also fix _force_shutdown task not being cancelled on graceful shutdown, and pending work_task left in TaskGroup causing a hang on stop.
Move initial release content to [0.0.1] - 2026-04-30 and document post-release changes under [Unreleased]: Supervisor architecture, batched task claiming, and direct dependency declarations. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
