* ci: add automated PR labeling system Add two independent workflows for PR auto-labeling: - Scope labels via actions/labeler (path glob matching) - Size, risk, and contributor tier via custom shell script Includes idempotent label bootstrap script (create-labels.sh). Co-Authored-By: Claude Opus 4.6 <[email protected]> * ci: temporarily use pull_request trigger for testing Switch to pull_request so workflows run from the PR branch. Will revert to pull_request_target before merge. Co-Authored-By: Claude Opus 4.6 <[email protected]> * fix(ci): use absolute path for search/issues API call gh api requires a leading slash for REST endpoints. Co-Authored-By: Claude Opus 4.6 <[email protected]> * fix(ci): use gh pr list instead of search API for contributor count The search/issues API returns 404 with the default GITHUB_TOKEN. gh pr list --state merged works with standard permissions. Co-Authored-By: Claude Opus 4.6 <[email protected]> * ci: revert to pull_request_target for fork PR support Restore pull_request_target trigger and base branch checkout now that testing is complete.
