Subject: [PATCH] chore(nix): version the build by git short SHA instead of
 package.json semver

flake.nix now uses self.shortRev (git HEAD short hash) as the derivation
version, so the store path is /nix/store/<hash>-9router-<shortsha> and any
deployed build traces to its exact source commit. Removes the package.json
version bump churn; the updater's deployed/current comparison switches to
git SHA.
