Replaces the cwd-hash identity with a random 5-char base36 suffix per launch, so two simultaneous `start <agent>` invocations against the same cwd no longer collide on container names. Each launch is its own bottle. State carries metadata: every prepare step writes ~/.claude-bottle/state/<identity>/metadata.json with the (agent_name, cwd, copy_cwd, started_at) the bottle was launched with. The new `cli.py resume <identity>` reads this metadata and re-launches a bottle pinned to the same identity — picking up the per-bottle Dockerfile (from a prior capability-block apply) and the transcript snapshot under the same state dir. - bottle_state.py: bottle_identity(agent_name) drops the cwd param and gains a random suffix; BottleMetadata dataclass + read/write/metadata_path helpers. - BottleSpec gains an optional identity field — resume sets it to pin the identity; start leaves it empty so prepare mints fresh. - prepare.py: writes metadata at launch time; uses spec.identity if provided (resume) else bottle_identity(agent_name) (fresh start). - start.py: extracted _launch_bottle from cmd_start so resume can share the launch core; prints `./cli.py resume <identity>` hint at session end. - cli/resume.py (new): reads metadata, reconstructs BottleSpec with the recorded identity + cwd, delegates to _launch_bottle. Errors clearly when no state exists for the given identity. - cli/__init__.py: registers `resume` in COMMANDS + usage. - dashboard.py: capability-block approval status line now appends the `resume <identity>` hint so the operator can copy-paste the rebuild command without leaving the TUI. Closes the rebuild loop in PRD 0016: agent calls capability-block → operator approves → bottle torn down with state preserved → status line shows resume command → operator runs it → replacement bottle boots with the new Dockerfile and prior transcript.
