Remove CodeQL workflow, add GitHub Pages deployment, and update project documentation

- Remove `codeql.yml` workflow for static security analysis.
- Add `pages.yml` workflow for deploying docs to GitHub Pages.
- Introduce `CODE_OF_CONDUCT.md` and `FUNDING.yml`.
- Update `README.md` with links to GitHub Pages and additional project setup details.
- Refine release workflow by splitting build and publish steps, and allowing publish errors for existing versions.
