The global build/ gitignore rule was silently excluding the PyInstaller
spec, desktop requirements, and build script under desktop/build/, so the
release workflow failed at "pip install -r requirements-desktop.txt" with
a missing-file error. Re-include just those source files while keeping the
build outputs (dist/, build-work/) and local venv ignored.
