This directory contains extensions to `ChatViewModel` to modularize its functionality.
|

- `ChatViewModel+Tor.swift`: Handles Tor lifecycle events and notifications.
|
||||
- `ChatViewModel+PrivateChat.swift`: Manages private chat logic, media transfers (images, voice notes), and file handling.
|
||||
- `ChatViewModel+Nostr.swift`: Contains all logic related to Nostr integration, Geohash channels, and Nostr identity management.
|
||||
|

The main `ChatViewModel.swift` retains core state, initialization, and coordination logic.
