Make the ECC 2.0 GitHub/Linear/handoff/roadmap progress-sync model part of the local observability readiness gate instead of leaving it as roadmap prose only.
- add `docs/architecture/progress-sync-contract.md` for GitHub, Linear, handoff, roadmap, and work-items sync
- add a `Tracker Sync` check to `scripts/observability-readiness.js`
- update observability tests with passing and missing-contract coverage
- update observability and GA roadmap docs so the local readiness gate is now 18/18 and records #1848 supply-chain hardening evidence
