/**
 * ConfigManager - Launch-time reaction role configuration management
 * 
 * Manages the static reaction role configurations that are loaded at bot startup.
 * Provides read-only access to configurations for role assignment actions.
 * 
 * Architecture rationale:
 * - Launch-time loading ensures configuration consistency during bot lifetime
 * - In-memory storage provides fast access without external dependencies
 * - Read-only access prevents accidental modification of critical configurations
 * - Array-based storage enables efficient lookup and iteration
 * 
 * Configuration format:
 * - from: Discord message ID to monitor
 * - emoji: Emoji that triggers the action
 * - action: Role assignment action to execute
 * - description: Human-readable description for admin reference
