## 🏗️ Architecture Implemented

### Database Layer
- ✅ SQLAlchemy 2.0 models (5 models: Project, Item, Link, Event, Agent)
- ✅ JSONType adapter (JSONB for PostgreSQL, JSON for SQLite)
- ✅ Connection pooling (pool_size=20, max_overflow=10)
- ✅ Health checks (dialect-aware)
- ✅ Migration support (create/drop tables)

### Configuration Layer
- ✅ Pydantic schemas with validation
- ✅ Configuration hierarchy (CLI > env > project > global)
- ✅ YAML-based config files
- ✅ Project-specific configuration
- ✅ Environment variable support

### CLI Layer
- ✅ Typer-based CLI framework
- ✅ Rich formatting for output
- ✅ Commands: config (init, show, set), db (status, migrate, rollback), project (init, list, switch)
- ✅ Version command
- ✅ Debug mode

### Test Infrastructure
- ✅ pytest framework with markers (unit, integration, e2e, slow, agent)
- ✅ Test fixtures (db_session, temp_config_dir, cli_runner)
- ✅ Test factories with faker (Item, Project, Link)
- ✅ Auto-cleanup after tests
