name: Release

# Tag-driven: push a `vX.Y.Z` tag matching addon.xml's version to cut a
# release. Builds the exact bytes that ship (git archive honors
# .gitattributes export-ignore, so tests/, tools/ and this .github/ tree
# never reach the zip) and attaches the zip to a new GitHub Release. See
# .github/RELEASING.md for the full tag-to-release flow.
