name: Auto-label PRs

# Apply area labels to PRs based on changed paths (see .github/labeler.yml).
# Complements the AI-based issue labeler (issue-auto-label.yml). Version (v1/v2)
# labels are handled separately by pr-version-label.yml.
#
# pull_request_target runs in the base repo context so it has the write token
# needed to label PRs from forks; actions/labeler only reads the diff file list
# (it never checks out or runs PR code), so this is safe.
