willuhd/PowerMetrics — reverse-engineered prompt

Build me a simple native Mac app called PowerMetrics that feels like Intel Power Gadget, but for Apple silicon. I want a clean live monitor that shows CPU power draw and clock speeds in easy to read graphs, especially for M5 chips with separate P, E, and S clusters. It should be lightweight, accurate, and not require sudo or any password prompts, so please read the raw hardware info directly instead of relying on a command line tool.

Make the UI familiar and minimal, with the same kind of frequency band look people expect from Intel PG. Let me change the polling rate and how much history the graph keeps. Focus on being stable and efficient enough to leave running while I work. If support for other Apple silicon generations can be added later, please structure it so that is easy to expand. Look up current Apple docs online if you need to.
