v0.6.3

Added

• --status now shows the worker assigned to each active issue (e.g. [worker-3]), matching the poll status summary. Worker assignments are persisted to ~/.autodev/workers.json by the running instance.
• --errors [IID] shows error details (message, stderr) for issues in error state. Without IID, shows all; with IID, shows a specific issue.
• --reset [IID] resets errored issues to pending (retry_count zeroed). Without IID, resets all; with IID, resets a specific issue.

Fixed

• Fix datetime('now') and datetime('now', '+N seconds') stored as literal strings instead of being evaluated by SQLite for started_at, finished_at, and next_retry_at fields. This broke automatic error retries since next_retry_at comparisons never matched.
