CODEX REPO HARDENING PROMPT

You are improving this repository's public open-source readiness and contributor experience.

Goals:
- complete the GitHub community health layer
- make the repo easier to adopt
- keep the repo honest, clean, and maintainable

Tasks:
1. Review the existing repo structure.
2. Check whether the following files exist and are good enough:
   - `CONTRIBUTING.md`
   - `CODE_OF_CONDUCT.md`
   - `SUPPORT.md`
   - `CHANGELOG.md`
   - `.github/ISSUE_TEMPLATE/*`
   - `.github/pull_request_template.md`
3. If any are missing or weak, draft improved versions.
4. Keep all wording aligned with this repo’s actual scope as a foundation kit.
5. Avoid overclaiming token savings or model compatibility.
6. Recommend any README additions that improve adoption without bloating it.
7. Suggest one small next release entry if changes are made.

Rules:
- Keep changes lightweight and practical.
- Prefer contributor clarity over legalistic boilerplate.
- Do not turn this repo into a framework or package unless explicitly asked.

At the end, give me:
- files added or updated
- why each file helps
- what to publish in the next release
