feat: Add four new personas and improve documentation

This commit introduces four new personas to the project:
- The Beetle: A harsh, critical anti-persona for stress-testing.
- The Guardian: A security-focused persona.
- The Novice: An inexperienced user persona for UX testing.
- The Prioritizer: A product-focused persona for value alignment.

This commit also improves the project's documentation in several ways based on user feedback:
- The Beetle persona is updated to offer insulting solutions, making it more dynamic.
- The `personas/README.md` and the root `README.md` are updated to include a complete, alphabetized list of all personas, each with a short description.
- The display text for the "Platforms" section in the root `README.md` is corrected for readability.
- All files have been formatted with Prettier.
