Madgique's Tickrate Changer

Added

• /tickrate <ticks> <player> command to change tickrate for a specific player
• --dontupdate flag for /tickrate setdefault command (sets default without updating current tickrate)
• Support for combined flags on setdefault: --dontsave --dontupdate (in any order)
• GitHub Actions workflow for automated publishing to Modrinth and CurseForge

Fixed

• Fixed 2-3 second freeze when changing tickrate (removed problematic setLastMs call in TimerMixin)
• Removed incomplete /tickrate setmap references from codebase

Changed

• Improved command system to support per-player tickrate control
• Enhanced setdefault command with more granular control over save and update behavior

Technical

• Properly configured dependencies: Architectury API, Cloth Config, Fabric API
• Added interface ITickrateChanger for timer manipulation
• Improved mixin structure for client tickrate changes
