refactor(install): port venv bootstrap, config tools and gitignore exclusions to installer

- Port .venv creation and dependency pip install bootstrap sequence from deploy/install.sh into scripts/install_mam.sh
- Include .env.example and scripts/generate-env.sh copies under rsync target deployment
- Add .venv/ to target gitignore list to prevent virtualenv bloating
- Add empty-UUID resume safety guard in INSTALL.md
