New Feature Documented

• Analyzes CI failures and suggests fixes WITHOUT implementing them
• Can be triggered via: fix-ci in custom prompt, @junie-agent fix-ci in comments, or automatic workflow_run failure events
• Uses get_pr_failed_checks_info MCP tool to retrieve detailed failure information
• Provides structured diagnosis with error details, root cause, and suggested fixes

All aspects of this new feature are now properly documented in README.md.
