docs: Enhance MONOREPO_CONVERSION_PLAN.md with improved details

- Specify production-ready implementation details for sal-git
  package.
- Add a detailed code review and quality assurance process
  section.
- Include comprehensive success metrics and validation checklists
  for production readiness.
- Improve security considerations and risk mitigation strategies.
- Add stricter code review criteria based on sal-git's conversion.
- Update README with security configurations and environment
  variables.
