docs: Update MONOREPO_CONVERSION_PLAN.md with text package status

- Marked the `text` package as production-ready in the
  conversion plan.
- Added quality metrics achieved for the `text` package,
  including test coverage, security features, and error
  handling.
- Updated the success metrics checklist to reflect the
  `text` package's completion.
