Add fern --eyw command to CLI reference

Added documentation for the fern --eyw command, which provides a quick
way to send an email to Deep, one of Fern's co-founders. This command:

- Opens a mailto link in the user's default email client
- Makes it easy for users to reach out with questions, feedback, or ideas
- Follows the same pattern as other person-specific CLI flags

The documentation includes:
- Command reference in the quick reference table
- Detailed accordion section with usage examples and tips
- Encouragement for community engagement
