- Added a runner policy that limits project build, test, audit, package, installer, dependency setup, and release work to `global-runner-1`, `global-runner-2`, and `global-runner-3`.
- Documented the supported Ubuntu labels: `ubuntu-latest`, `ubuntu-24.04`, and `ubuntu-22.04`.
- Clarified that heavy project commands must not run on the user's local machine and that Windows or macOS runners should be replaced with Linux-compatible workflow workarounds.
- Split the repository documentation into a human-facing setup `README.md` and a repository-specific agent instruction file in `AGENTS.md`.
- Expanded the human README with full new-repository setup guidance, SSH setup, Gitea token permissions, local token configuration, repository secrets, package publishing, and release checks.
- Documented the recommended Gitea token permission matrix shown in the token UI.
- Added agent guidance to create focused tracker issues for actionable follow-up work that is outside the current scope or independently parallelizable.
- Added safeguards against creating vague, duplicate, or sensitive public issues.
- Updated handoff guidance to use `docs/agent-handoff.md` when no issue tracker is available or the details are too sensitive for public issues.
