Kevin Veen-Birkenbach 0c90e984ad Refine setup workflows and add architecture map
- Split virgin tests into separate root and user GitHub Actions workflows
  (test-virgin-root, test-virgin-user) and adjust Arch container flows
- Introduce scripts/installation/venv-create.sh and reuse it from
  scripts/installation/main.sh with separate root/system and user/dev paths
- Add PKGMGR architecture & setup map (assets/map.png) and section in README
  with link to the up-to-date master page
- Simplify README by removing outdated Docker quickstart, usage examples,
  and AI footer
- Extend .gitignore to exclude src/source artifacts

# Responsibilities:
# - If inside a Nix shell (IN_NIX_SHELL=1):
# * Skip venv creation and dependency installation
# * Run `python3 main.py install`
# - If running as root (EUID=0):
# * Run system-level installer (run-package.sh)
# - Otherwise (normal user):
# * Create ~/.venvs/pkgmgr virtual environment if missing
# * Install Python dependencies into that venv
# * Append auto-activation to ~/.bashrc and ~/.zshrc
# * Run `main.py install` using the venv Python
