Creates migration 000409 with the database foundation for pausing and resuming task workspaces. The task_snapshots table stores conversation history (AgentAPI messages) so users can view task logs even when the workspace is stopped. Each task gets one snapshot, overwritten on each pause. Three new build_reason values (task_auto_pause, task_manual_pause, task_resume) let us distinguish task lifecycle events in telemetry and audit logs from regular workspace operations. Uses a regular table rather than UNLOGGED for snapshots. While UNLOGGED would be faster, losing snapshots on database crash creates user confusion (logs disappear until next pause). We can switch to UNLOGGED post-GA if write performance becomes a problem. Closes coder/internal#1250
