feat: implement remaining action-register items and Phase B governance infrastructure

Completes 8 action-register items and builds Phase B foundation:

Security (S-P2):
- S-P2-4: Make Bandit blocking in CI (remove || echo fallback)
- S-P2-1: Emit missing_chain_key warning in audit_chain._load_run_key

UX (U-P1/2):
- U-P1-5: Remove --no-tui from all module documentation; replace with
  '(removed)' notes explaining it was never implemented
- U-P2-5: Clean up minor help-text/docstring issues (rendering.py)

Phase B governance infrastructure:
- PR template: add Action ID, Risk Class, and Self-Review Checklist fields
  per review-system.md G2/G4/G9
- scripts/check_action_register_link.py: pre-commit hook enforcing G9
- scripts/check_github_url_consistency.py: validate canonical URL (U-P0-1)
- scripts/check_god_modules.py: enforce 800-line thin-harness rule
- scripts/high_risk_paths.yaml: centralized config for G4 triggers
- .pre-commit-config.yaml: register three new hooks

Governance documentation:
- 06-action-register.md: add Status/Owner/Evidence columns; track 12 items
  as done or already-implemented; add Phase B infrastructure table

Constraint: additive only (test assertions kept); Phase B hooks are
pre-commit only, not yet CI blocking per phased rollout plan
Tested: docs inventory/verify_docs/OKF/release evidence all green
Confidence: high

Action: S-P2-4, S-P2-1, U-P1-5, U-P2-5

 ### Rich Interactivity vs. Headless Compatibility

+**Resolution:** All non-interactive usage goes through `teaagent run` (CLI, no TUI). TUI is `teaagent chat` only. (The `--no-tui` flag was documented but never implemented and has been removed from documentation.)  
 **Break-even:** Not applicable — the split is intentional and correct. Monitor if users route interactive work through `run` to avoid TUI friction (signals UX issue in chat).
