How It Works

User → Heimdal CLI → Package Database (60+ packages)
                    ├─→ Homebrew / APT / DNF / Pacman / MAS
                    ├─→ Dotfile Management (GNU Stow compatible)
                    ├─→ Secret Management (OS Keychain)
                    └─→ Git Sync (with state management)

The package database is downloaded from GitHub Releases and cached locally (~/.heimdal/cache/packages.db). It auto-updates every 7 days.
