refactor: update issue-fixer mode to use GitHub CLI instead of MCP

[hannesrudolph]

Description

This PR updates the issue-fixer mode to use GitHub CLI (gh) for all GitHub operations instead of the GitHub MCP server. This simplifies the setup and removes external dependencies.

Changes Made

Mode Configuration Updates

• Removed mcp from the groups list in .roomodes
• Updated roleDefinition to mention GitHub CLI usage
• Made the mode work with any GitHub repository (not just RooCodeInc/Roo-Code)
• Simplified whenToUse description to focus only on issue fixing

Workflow Updates

• All GitHub operations now use gh commands:
  • gh issue view for retrieving issues
  • gh issue view --comments for getting comments
  • gh pr create for creating pull requests
  • gh pr checks --watch for monitoring CI/CD
  • gh repo fork for forking when needed
  • gh api for advanced operations

File Changes

• Renamed 4_github_mcp_tool_usage.xml to 4_github_cli_usage.xml with comprehensive CLI documentation
• Updated 5_pull_request_workflow.xml to use dynamic repository references
• Removed pr_comments section from 8_github_communication_guidelines.xml
• Removed 9_pr_review_workflow.xml (functionality moved to pr-fixer mode)

Benefits

1. No External Dependencies: Only requires standard GitHub CLI tool
2. Simpler Setup: Users authenticate once with gh auth login
3. Works with Any Repository: Dynamically extracts repo info from issue URLs
4. Clearer Scope: Mode focuses exclusively on issue fixing

Testing

• Verified all XML files are well-formed
• Checked that all GitHub CLI commands are properly documented
• Ensured mode configuration is valid
• All lint checks pass

Checklist

• Code follows project style guidelines
• Self-review completed
• Documentation updated
• No breaking changes for existing users

• The syntax declaration omits the --limit flag shown in examples. Update it to gh search code "[search-query]" --repo [owner]/[repo] --limit [number] for consistency with usage examples.

      <syntax>gh search code "[search-query]" --repo [owner]/[repo]</syntax>
