Add LibraryMethodAnalysisTrigger to identify unused GitHub API methods - #304

🎯 Summary

This PR implements issue #97 by adding a comprehensive library method analysis system to the GitHub API Bot. The new LibraryMethodAnalysisTrigger can analyze the codebase to identify unused GitHub API methods and suggest optimizations for better library utilization.

🚀 Key Features

Library Method Analysis

• Unused Method Detection: Scans all available Octokit GitHub API methods and identifies which ones are not currently being used
• Usage Pattern Analysis: Analyzes current API usage patterns and identifies the most frequently used methods and API categories
• Code Optimization Suggestions: Detects problematic patterns like .Result and .Wait() usage that can cause deadlocks

Actionable Recommendations

• Async/Await Improvements: Identifies places where blocking calls should be replaced with proper async patterns
• Batching Opportunities: Suggests where individual API calls could be batched for better performance
• Caching Suggestions: Recommends caching strategies for frequently accessed data that doesn't change often

Detailed Reporting

• Markdown Reports: Generates comprehensive, human-readable reports with categorized suggestions
• Usage Statistics: Shows most used API categories and methods with usage counts
• Code Examples: Provides specific examples and recommendations for improvements

🔧 How It Works

The trigger activates when an issue contains keywords like:

• "analyze library usage"
• "find library methods"
• "library method analysis" (in issue body)

When activated, it:

1. Scans the codebase to identify all current GitHub API method usage
2. Catalogs available methods from the Octokit library using reflection
3. Performs analysis comparing available vs. used methods
4. Generates suggestions for optimizations and improvements
5. Posts a detailed report as a comment on the triggering issue
6. Closes the issue automatically after posting the analysis

📊 Example Report Sections

The generated report includes:

• Current Usage Patterns: Most used API categories and methods with statistics
• Optimization Opportunities: Categorized suggestions for improvements (Async/Await, Batching, Caching)
• Available but Unused Methods: Organized by API category to discover new capabilities
• Summary: Key metrics and recommendations overview

🛠️ Technical Implementation

• Reflection-based Analysis: Uses .NET reflection to discover all available Octokit methods
• Pattern Matching: Employs sophisticated regex and string analysis to identify API usage in source code
• Modular Design: Built as a standard trigger that integrates seamlessly with the existing bot infrastructure
• Robust Error Handling: Gracefully handles analysis failures and reports errors appropriately

🧪 Integration

• Added the new trigger to the main IssueTracker in Program.cs
• Follows established patterns from existing triggers like HelloWorldTrigger and ProtectDefaultBranchTrigger
• Maintains compatibility with existing bot functionality

✅ Testing

• Solution builds successfully with no compilation errors
• Follows existing code conventions and documentation patterns
• Ready for production deployment

Fixes #97
