Add AudioPriorityBar to Homebrew Cask

[thevrus]

Hi Tobias,

Would you consider adding AudioPriorityBar to Homebrew Cask? It’d make installation easier for users who prefer brew install —cask audiopriority-bar.

The app meets Homebrew’s requirements:

• Pre-built binaries are available via GitHub Releases.
• macOS 13.0+ is acceptable.
• The Notability threshold (75+ stars) is reachable given community interest.

The process is straightforward and documented in the Homebrew Cask Cookbook.

Thanks for building this useful tool!
