Replace exec.Command git clone/pull with go-git's PlainCloneContext
and Worktree.Pull. Removes git binary dependency — only makepkg and
pacman are needed on the host now.
Native Go implementation using the AUR RPC v5 API for search/info
queries and git+makepkg+pacman for building and installing packages.
Implements:
- Manager (full: Install, Remove, Purge, Upgrade, Update, List, Search,
Info, IsInstalled, Version)
- VersionQuerier (LatestVersion, ListUpgrades, UpgradeAvailable, VersionCmp)
- Cleaner (Autoremove via pacman, Clean build dir)
- PackageUpgrader (UpgradePackages)
Key design decisions:
- No CLI wrapper (paru/yay) — uses AUR RPC API directly + git clone
- Packages are built with makepkg and installed via pacman -U
- Foreign packages (pacman -Qm) are treated as AUR packages for List
- Batch RPC queries (rpcInfoMulti) for efficient upgrade checks
- Configurable build directory and makepkg flags
- Not added to detect.Default() candidates (AUR supplements pacman,
not replaces it) but available via detect.ByName("aur")
