Implement Discord bot with programming language role synchronization
This commit adds a comprehensive Discord bot that synchronizes user roles with programming languages detected from their GitHub repositories. Features: - Analyzes public GitHub repositories to detect programming languages - Automatically assigns/removes Discord roles based on language usage - Supports 15+ programming languages with configurable role mappings - User-friendly commands: !sync-roles, !my-sync, !check-languages, !help - Rich Discord embeds with detailed language statistics - Comprehensive logging and error handling - Integration with existing LinksPlatform storage system Technical implementation: - Modern .NET 8 architecture with dependency injection - Discord.Net library for Discord API integration - Octokit for GitHub API integration - Microsoft.Extensions.Hosting for service lifecycle management - Configurable through appsettings.json - Added supporting methods to FileStorage for key-value mappings 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
