fix(bot): Fix duplicate notifications, add TypeScript types, validation, and database migrations
## 🐛 Bug Fixes
### 1. Triple Duplicate Notifications
- Remove duplicate MessageCreate event handler in index.ts
- Add message ID deduplication in xpSystem.ts to prevent race conditions
- Implement smart cleanup using Discord snowflake timestamps
### 2. "No XP Data Yet" Error
- Add enhanced error logging for database operations
- Improve upsert handling with ignoreDuplicates: false
- Add .select() to verify insert/update success
- Fix timing issues between XP processing and /rank command
## ✨ New Features
### Type Safety
- Create types/database.ts with proper database interfaces
- Create types/commands.ts with command type definitions
- Remove all 'any' type usage (9 instances fixed)
- Add proper TypeScript types throughout codebase
### Input Validation
- Create utils/validation.ts with comprehensive validation functions
- Add sanitization for user-generated content
- Validate XP configuration values
- Validate message templates with placeholder checking
- Prevent control characters and injection attacks
### Configuration Management

- Create constants/errorCodes.ts for error code definitions
- Centralize magic strings and configuration values
### Health Monitoring & Error Handling
- Add graceful shutdown handlers (SIGINT, SIGTERM)
- Implement Discord client error monitoring
- Add unhandled promise rejection handlers
- Add uncaught exception handlers with safe exit
### Database Migrations
- Create comprehensive migration script (001_create_discord_tables.sql)

- Include migration README with detailed instructions
- Create 8 tables with proper indexes, constraints, and RLS policies
- Add helpful database views for leaderboards and rewards
- Include verification queries and troubleshooting guide
### Documentation
- Add comprehensive README.md with setup instructions
- Create .env.example with all required environment variables
- Document all commands, configuration, and database schema
- Add troubleshooting section and security notes
## 🔧 Technical Improvements

- Replace Collection<string, any> with proper types
- Fix level type (any → number | string)
- Add proper error messages and logging
- Improve code organization and structure
### Performance
- Add cooldown cleanup to prevent memory leaks
- Optimize database queries with proper indexes
- Add message processing deduplication
