Releases are now fully handled by create-release.yml, which is
triggered manually via the GitHub UI or `make release`. The separate
tag-triggered release.yml is no longer needed.
Move the TinyGo build, packaging, and GitHub release creation from
release.yml into create-release.yml. This avoids the GITHUB_TOKEN
limitation where pushes from a workflow don't trigger other workflows.
release.yml is kept as a fallback for manually pushed tags.
