feat: add .architect/ project mapping system with architect-indexer agent and Docker containerization

- Add .architect/ directory structure (10 template files) as project brain for agent orientation
- Add architect-indexer agent that scans codebase and generates structured architecture docs
- Add Docker containerization: Dockerfile.architect-indexer, docker-compose.architect.yml
- Add TypeScript project-mapper module with staleness detection and context injection
- Add /index-project command, architect-first-contact rule, project-mapping skill
- Integrate orchestrator first-contact check: triggers indexing before any task delegation
- Add npm arch:* scripts for Docker-based indexing workflow
- Register agent in capability-index.yaml and AGENTS.md
