chore(compliance): remove dual-truth 6A2 drift + old contractile schema, fix ROADMAP

- Delete stale root-level STATE/META/ECOSYSTEM.a2ml (shadowed canonical 6a2/ files)
- Delete old-format ADJUST/INTENT/MUST/TRUST.contractile (pre-trident schema)
- Rewrite ROADMAP.adoc with actual Nash Equilibrium phases and ADR log
