PRD 0018 chunk 4. `claude-bottle cleanup` now derives its work
from `docker compose ls --all --format json`, filtered to projects
whose name starts with `claude-bottle-`. Per project: one `compose
down --volumes` removes the containers + the compose-managed
networks atomically.
The plan also enumerates three fallback buckets:
- Stray containers — `claude-bottle-*` containers with no
`com.docker.compose.project` label (left over from pre-compose
code paths). Cleared via `docker rm -f`.
- Stray networks — `claude-bottle-*` networks with no compose
project label. Cleared via `docker network rm`.
- Orphan state dirs — per-bottle `~/.claude-bottle/state/<id>/`
dirs with no live project AND no `.preserve` marker. The
`.preserve` marker (capability-block or auto-preserve-on-crash)
explicitly opts-out of reaping; manual `rm -rf` is the only
path for preserved state.
cli/cleanup.py collapses to a single y/N prompt — backend.prepare_cleanup
returns everything in one plan, backend.cleanup processes everything,
no more double-prompt for state. The CLI-side state-dir enumeration
+ `_state_summary` flags from PR #25 are gone; the backend's
orphan-detection rules subsume them.
