Additional Notes

Security Review

• Self-hosted runner exposure via pull_request_target (.github/workflows/release-drafter.yml): The autolabel-pr job triggers on pull_request_target from any fork PR and runs on a self-hosted runner. For a public repo this lets any external contributor execute jobs on internal infrastructure. Recommend switching the autolabeler job to ubuntu-latest.

Important Files Changed

Filename	Overview
.github/workflows/release-drafter.yml	New workflow using pull_request_target with self-hosted runners — security risk for a public repo; autolabeler and release-draft jobs are otherwise correctly structured
.github/release-drafter.yml	New release-drafter config with full autolabeler; style label is defined but missing from categories and version-resolver patch labels, causing style PRs to be dropped from release notes
.github/CONTRIBUTING.md	Adds Conventional Commits guidance and a complete branch naming table covering all commit types; minor editorial cleanup throughout
