The old workflow grepped CMakeLists.txt for the first "VERSION X.Y" match,
which was cmake_minimum_required's own version rather than the project's,
mangling it to 3.27.0.0 on the first real bump. PLUGIN_VERSION in .env is
now the single source of truth for both CMakeLists.txt and flake.nix, and
the workflow's bump/commit steps only ever touch that one file.
