Build 44: fix recurring macOS release build

release.yml's `files:` upload globs still used ${{ inputs.tag }}, which is empty
on a `release: published` event, so the auto-built macOS universal zip never
matched its filename and didn't attach — the job went green while uploading
nothing. Use the inputs.tag || release.tag_name fallback for the globs too.

Also fix the CI build number: building from the public single-commit squash
makes `git rev-list b51a46b..HEAD` fail (the fork base isn't an ancestor), so
build.rs fell back to "Build dev". build.rs now honours a GOBLIN_BUILD env
override and release.yml passes GOBLIN_BUILD=${TAG#build}, so CI artifacts carry
the real build number.
