Implemented comprehensive mute management system and admin permission handling:
**MuteManager (Local Storage)**:
- JSON-based persistent storage for muted players
- Stores mute data in Mods/BotCommandMod/Data/muted_players.json
- Supports temporary and permanent mutes with reasons
- Auto-cleanup of expired mutes on load
- Thread-safe file operations with locking
- Manual JSON serialization to avoid external dependencies
**AdminPermissionManager**:
- Reads serveradmin.xml to load admin users (permission_level < 1000)
- Auto-discovery of serveradmin.xml location
- Caches admin list in memory for fast permission checks
- Supports reload command to refresh admin list
**Chat Command System**:
- Harmony patch on ChatCommandManager.ProcessCommand
- Blocks chat/commands from muted players with informative messages
- New /bot commands for admins:
- /bot mute <player> [minutes] [reason] - Mute a player
- /bot unmute <player> - Unmute a player
- /bot mutelist - List all muted players
- /bot admins - Show all loaded admins
- /bot reload - Reload serveradmin.xml
**Build System**:
- Added System.Xml.dll and System.Xml.Linq.dll references for XML parsing
All features are fully functional and ready for testing.
