rzuastiandClaude Opus 4.8 4a1fe60ec3 Derive the version from the Cargo/pubspec manifests
The version string was duplicated across six places. Collapse it to two
ecosystem sources of truth and derive the rest:

- backend/src/web_server.rs: omit the OpenAPI info.version so utoipa fills
  it from CARGO_PKG_VERSION (backend/Cargo.toml); add a test pinning this.
- nix/package.nix: read the version from backend/Cargo.toml via fromTOML.
- nix/frontend.nix: read the version from frontend/pubspec.yaml by splitting
  into lines (a whole-file regex triggers catastrophic backtracking in Nix's
  regex engine).
- frontend/lib/about/about.dart: read the version at runtime via
  package_info_plus instead of a hardcoded constant.

Also drop frontend/pubspec.lock.json: it is unreferenced (Nix's
autoPubspecLock generates its own JSON from pubspec.lock) and was going stale.
