docs: update for container config DB, on-wake, and CLI scope

- CLAUDE.md: new key files, updated groups verbs, rewritten self-mod
  section, new Container Config and Container Restart sections
- db-central.md: container_configs table (§1.15), migrations 014+015
- db-session.md: messages_in schema with trigger, source_session_id,
  on_wake columns
- schema.ts: comment no longer references disk-based config
- cli.instructions.md: rewritten for scope-aware usage, auto-fill,
  restart/config ops, group-scoped examples
