fix: Refactor token references in workflows and documentation

- Updated references from `CPMP_TOKEN` to `CHARON_TOKEN` in beta release draft PR body, beta release PR body, and GitHub setup documentation.
- Enhanced clarity in documentation regarding the use of `GITHUB_TOKEN` and fallback options.
- Removed outdated sections from the archived plan for the Docs-to-Issues workflow fix, streamlining the document.
- Initiated integration of Staticcheck into pre-commit hooks to improve code quality, including updates to Makefile, VS Code tasks, and documentation.
