fix: CI workflow, pre-commit config, and bot TIMELINE_CHANNEL crash

- Fix jq parse error in detect-changes when BASE is all zeros
- Relax pre-commit flake8 rules to ignore existing violations
- Simplify CI to run pre-commit from repo root
- Make TIMELINE_CHANNEL optional to prevent bot crash on startup
