homedir-manager

Use on demand to reconcile a Mac's GUI-changed settings into version control — when the user says "reconcile my mac defaults", "capture my macOS settings", or after they've changed System Settings and want the keepers tracked. Drives homedir-manager's `defaults` verb (capture/drift/apply) against a versioned desired-state file.

Use when adding, changing, deploying, onboarding, or auditing homedir-manager content repos — the marker-based symlink deployment system that manages dotfiles and config across your machines. Covers the update workflow, the manifest, OS-splitting, secrets, new-machine onboarding, and the audit process.
