feat(cli): migrate aipass init from devpulse prototype (#48)

Restructure init_project.py into CLI's 3-layer architecture:
- Handler: apps/handlers/init/bootstrap.py (pure Python business logic)
- Module: apps/modules/init_project.py (thin orchestration)
- Wiring: cli.py routes `aipass init` via _handle_aipass()

Command: drone @cli aipass init [target_dir] [project_name]
