feat: Timmy orchestrator — local Ollama-powered backlog brain

- timmy-orchestrator.sh: 5-min cycle, assigns unassigned issues to claude,
  reviews open PRs via qwen3:30b, merges/comments/closes as needed
- Single instance guard via pidfile
- ops-panel: shows Timmy status (Ollama model, last action)
- ops-helpers: ops-wake-timmy / ops-kill-timmy commands
- Timmy is the brain, Claude/Gemini/Kimi are the hands
