Previously `make fetch-gui` extracted the GUI release into cmd/gui/dist/ and the unpacked tree was embedded uncompressed via `//go:embed dist`. This commits and embeds the GUI bundle (dist.zip) and its release tag (dist.tag) to the repo so: - the rclone binary is smaller - `go build` works on a fresh clone without first running fetch-gui - a given commit pins an exact GUI version The "Fetch GUI" step was removed from .github/workflows/build.yml.
