Overview

This issue is a follow-up to #353 to implement comprehensive documentation improvements regarding SSH authentication best practices in MyCoder.

Proposed Changes

1. Add a new section "SSH vs. HTTPS Authentication" to clearly recommend SSH over HTTPS
2. Expand the existing SSH Passphrase section with more comprehensive guidance for all platforms
3. Add a troubleshooting section for common SSH issues
4. Update the GitHub Action documentation with better SSH guidance
5. Add links to GitHub's official SSH documentation
