name: Issue template guard

# Blank / free-form issues bypass `blank_issues_enabled: false` (it only hides
# the chooser link — the CLI, API and direct URLs still create template-less
# issues). This guard enforces the policy after the fact: an issue opened by
# someone WITHOUT write access that did not go through a template (no template
# label) is commented on and closed. Properly-filed bug reports / feature
# requests (which carry `bug` / `enhancement`) and anyone with write access are
# left alone.
#
# Note: workflows for `issues` events run from the file on the DEFAULT branch,
# so this only takes effect once it lands on `main`.
