Discord Bot: Synchronize programming languages roles with languages current user knows - #298

Summary

This PR implements a comprehensive Discord bot that automatically synchronizes programming language roles with the languages users actually know based on their GitHub repositories.

Features

✅ Automatic Language Detection: Analyzes public GitHub repositories to detect programming languages and their usage
✅ Smart Role Management: Automatically assigns/removes Discord roles based on actual language usage
✅ 15+ Language Support: C#, JavaScript, TypeScript, Python, Java, C++, Go, Rust, Ruby, PHP, Swift, Kotlin, Dart, Scala, F#, Clojure, Haskell
✅ User-Friendly Commands:

• !sync-roles <github-username> - Links GitHub account and synchronizes roles
• !my-sync - Re-synchronizes using previously linked account
• !check-languages <github-username> - Shows detected languages without changing roles
• !help - Shows available commands

✅ Rich User Experience: Beautiful Discord embeds with detailed language statistics and percentages
✅ Configurable: Custom role mappings and thresholds via appsettings.json
✅ Robust Error Handling: Comprehensive logging and graceful error recovery
✅ Modern Architecture: .NET 8, dependency injection, hosted services

Technical Implementation

• Discord.Net 3.15.3 for Discord API integration
• Octokit 13.0.1 for GitHub API integration
• Microsoft.Extensions.Hosting for service lifecycle management
• Integration with existing LinksPlatform storage system
• Enhanced FileStorage with key-value mapping support for user-GitHub associations

Test Plan

• Build succeeds without errors
• Project integrates with existing solution structure
• Storage layer enhanced with backward compatibility
• Configuration structure provides flexibility for role mappings
• Command structure follows Discord.Net best practices
• GitHub API integration handles rate limits and errors gracefully

Configuration Required

To deploy this bot, server administrators need to:

1. Create Discord bot application and get token
2. Generate GitHub personal access token for API access
3. Create programming language roles in Discord server
4. Update appsettings.json with tokens and role mappings
5. Add bot to server with appropriate permissions (Manage Roles, Send Messages, etc.)
