Replace fragile cron+shell approach with `poc-memory daemon` — a single
long-running process using jobkit for worker pool, status tracking,
retry, cancellation, and resource pools.
Jobs:
- session-watcher: detects ended Claude sessions, triggers extraction
- scheduler: runs daily decay, consolidation, knowledge loop, digests
- health: periodic graph metrics check
- All Sonnet API calls serialized through a ResourcePool(1)
Status queryable via `poc-memory daemon status`, structured log via
`poc-memory daemon log`. Phase 1: shells out to existing subcommands.
