0.32.0: The llama has left the barn

LlamaBarn is now Llama. It's the same app with a new name, and your settings and downloaded models carry over automatically.

Because of the rename, this update isn't automatic -- download and install the new app.

Also in this release:

• Default server port is now 8080 to match llama.cpp, was 2276
• Set a custom port in Settings, including 2276 if you relied on the old one
• Deeplinks now use the llama:// scheme; llamabarn:// still works
