CHECKPOINT: Interactive soundboard and refactored SFX system

Major Features Implemented:
- Complete Discord.js v14 modernization from v12 with hybrid command system
- SQLite database for dynamic guild configuration management
- Interactive soundboard with categorized button interface (/soundboard)
- Three-tier SFX interface: prefix (!sfx), autocomplete (/sfx), and visual soundboard
- Auto-registration system for public bot distribution
- Soft delete guild management preserving configurations

Technical Improvements:
- Refactored SFX playing into reusable service methods (playSFXInteraction/playSFXMessage)
- Smart markdown chunking that respects code block boundaries
- High-performance caching for 275+ sound effects with autocomplete optimization
- Modern Discord.js v14 patterns (MessageFlags.Ephemeral, proper intents)
- Fixed security vulnerability in @discordjs/opus with pnpm overrides
- Docker deployment with Node 20 and npm for reliable SQLite compilation

Interactive Soundboard Features:
- Category-based navigation with buttons (GENERAL, NERDS, TWIN PEAKS, etc.)
- Pagination support for large categories (16 sounds per page, 4 per row)
- Real-time status updates (Playing → Finished playing)
- Navigation buttons (Previous/Next/Back to Categories)
- Ephemeral responses for clean chat experience

Database System:
- Auto-migration from config.json to SQLite on first run
- /config slash commands for live server configuration
- Scheduled events with timezone support (object and cron formats)
- Guild auto-registration with welcome messages for new servers

Current State: Fully functional modern Discord bot ready for public distribution
