Fix missing dependencies and directories for Debian build

- Add psutil dependency to pyproject.toml and debian/control
- Fix pyproject.toml license format (use string instead of table)
- Create missing directories referenced in .install files:
  - templates/, chroot.d/, mounts/ for filesystem package
  - default-configs/ for configs package
  - docs/plugins/ for plugins package
  - dev/, docs/api/, include/, scripts/dev/ for dev package
  - cache-plugins/, cache.d/, docs/cache/ for cache package
- Add placeholder README.md files to prevent empty directories
- Update CI dependencies to include python3-psutil

Fixes:
- ModuleNotFoundError: No module named 'psutil' in performance.py
- Missing files errors in dh_install step
- pyproject.toml license deprecation warnings

Ready for successful Debian package build!
