chore: deploy UX infrastructure (contractile.just, .well-known, manifest)

Batch deployment of missing UX infrastructure files:
- contractile.just (policy enforcement recipes)
- .well-known/ (ai.txt, humans.txt, security.txt, groove/)
- 0-AI-MANIFEST.a2ml (AI agent entry point)
- agent_instructions/ (methodology, coverage, debt)
- Justfile with doctor/heal/tour/help-me recipes
- setup.sh bootstrap script
- llm-warmup-user.md
