Steps to reproduce

1. run the app
2. observe only 4 of your cores being used
3. 🤷

Expected behaviour

"The app will hog all cores by default" according to the docs

Actual behaviour

it uses 4

(rest of the template not really relevant)

https://github.com/nextcloud/stt_whisper2/blob/main/lib/main.py#L63C20-L63C58 initialises the Model(s) with default parameters, which for cpu_threads is 0, but apparently that actually means 4(?)
see https://github.com/SYSTRAN/faster-whisper/blob/d3bfd0a305eb9d97c08047c82149c1998cc90fcb/faster_whisper/transcribe.py#L619

Start at lib/main.py line 63, where Model is initialized with default parameters, then compare the cpu_threads handling in faster-whisper's transcribe.py around line 619. Reproduce the four-core behavior and verify what a default value of 0 means; document the expected default behavior and the change needed to make the application match it.
