The commit updates the handoff flake dependency from a local path to a GitHub repository. This changes the source URL from a local path "/home/servius/Projects/handoff" to "github:xatuke/handoff" and updates the corresponding lock file entries with new revision and hash information. The change affects: - flake.nix: Updated handoff url from path to github - flake.lock: Updated handoff locked and original fields to reflect github source This ensures the project uses the upstream handoff repository instead of a local development path.
