digimata/quill ? reverse-engineered prompt

Build me a tiny macOS menu bar app called quill that records meetings completely on the computer, without sending anything to the cloud.

I want one click to start and stop recording, with the mic and the system audio saved as two separate tracks. When I stop, it should automatically transcribe the recording on device and create a clean transcript with speaker labels, plus a readable markdown version. It should save each session into its own dated folder in a Recordings directory, along with the audio files, timing info, and a log if something goes wrong.

Please make it work as a background menu bar utility with a simple command line way to run it, install it at login, and check whether permissions and transcription models are ready. If transcription is not available, it should still record. If you need to look up current docs online for the macOS audio capture pieces, go ahead.
