v1.1.0

feat: loop engineering (iterate→verify→fix) — v1.1.0

hivemux loop <name> --goal … --check "<cmd>" --max N: drive an agent through
iterate→verify→fix cycles until the verifier passes or a stop condition hits
(max iters / cost cap / context cap). On pass: optional --commit / --pr.
- verifier: shell check (exit 0) or LLM judge (--rubric)
- --fleet N: same goal across N isolated agents
- --install-hook: Claude Code Stop hook → `hivemux notify -s done` (closes the loop)

Decision state-machine + shell verifier unit-tested; full controller validated
end-to-end with a real shell verifier + simulated turn signal (fail→retry→pass).
