Subject: [PATCH] flake: explicitly configure commit-lock-file-summary
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Sets `nixConfig.commit-lock-file-summary` to "flake: Update", matching
the default used by `ci/update`. This ensures consistency when running
`nix flake update --commit-lock-file` or `nix flake lock --commit-lock-file`
manually.

Note: manual updates are discouraged. The `nix-build ci -A update`
script should be used to update flakes. This ensures both root and dev
lockfiles — as well as `version-info.toml` — are kept in sync.
