Alexander Whitestone 3cf9f0de5e feat(ops): deadman switch, model health check, issue filter
Closes #115: bin/deadman-switch.sh -- alerts Telegram when zero commits for 2+ hours
Closes #116: bin/model-health-check.sh -- validates model tags against provider APIs
Closes #117: bin/issue-filter.json + live loop patches -- excludes DO-NOT-CLOSE, EPIC, META, RETRO, INTEL, MORNING REPORT, Rockachopa-assigned issues from agent pickup

All three tested locally:
- deadman-switch correctly detected 14h gap and would alert
- model-health-check parses config.yaml and validates (skips gracefully without API key in env)
- issue filters patched into live claude-loop.sh and gemini-loop.sh
