Add any model you want using symlinks

Hey, love what you're doing here. If I could make a suggestion, as a lot of us come from other dictation apps and already have downloaded models on our Macs, can we have a way to add a symlink of our model to your model folder. I've tried this out already, using Application Support folders and navigating to the models section, but I can't seem to figuire out how to proceed from there.

Once again, love what you're doing here and thank you so much. ❤️

Start by reviewing how the macOS app handles its Application Support folders and the model section mentioned in the issue. Determine how an externally linked model should be discovered and what user-visible behavior confirms that it can be selected and used.
