docs(rfc): Update RFC 0001 with refinement dialogue consensus
Major updates from 12-round alignment dialogue (unanimous consensus):
Architecture:
- Hybrid coordination: SQLite IPC for real-time hints + Git PRs for durable changes
- SQLite sessions.db replaces JSON file for session coordination
- SQLite cache.db for export/contract/validation caching
Commands:
- Reduced to 5 MVP commands: status, sync, worktree, pr, check
- Admin commands under `blue realm admin` subcommand
- Added `blue realm check` with modes: exporter, importer, contract, compatibility
Contracts:
- Added `owner` field (one exporter per contract)
- Added `compatibility: {backwards, forwards}` rules
- Added `validation:` hooks with ci_only option
- Semver ranges in import bindings
Trust & Governance:
- Explicit trust.permissions model
- Contract ownership enforcement
- Cycle detection and prevention
Credentials:
- Layered: env → git credential → keychain → config
- GitHub App auth support for CI
Conflict Resolution:
- Ownership + semver + git rebase strategy
- Stale bindings as soft warnings
