v0.8.6-beta7

Back from hiatus - this is a small update with an updated llama.cpp build and comfort features.

Features:

• Added option to run TTS while generating!
• Users are now linked to specific Chats. When loading a chat, it will automatically load the relevant User persona used when the chat was created.
  • You can disable this in Settings
  • You can change the linked User in the Chat Drawer
  • Old Chats will not have any users linked

Changes:

• Updated llama.cpp - should be able to use Gemma 3 QAT (Though the GGUFs are said to be buggy) and RWKV7

Fixes:

• Textbox popups rendering incorrectly.
• ChatText height not updating.
