v1.4.2

Added (v1.4.0)

• Auto-Update Notification System: New !giveaway update command to check for updates from GitHub.
• Update Service: Automatically checks RELEASE_NOTES.md on startup and alerts via Toast/Chat if a new version is available.
• Privacy-Focused: Downloads updates to a local updates/ folder and notifies via Toast to avoid exposing file paths
  in streaming chat.

Fixed (v1.4.0)

• Toast Notifications: Fixed CPHAdapter.ShowToastNotification signature to correctly invoke Streamer.bot method
  (was causing crashes).
• Code Quality: Addressed nullability warnings in UpdateService and refactored it for better encapsulation.
