Task Manager, now running on my Mac

I wanted Windows Task Manager's useful layout in a native Mac app, and the first working build is now running locally. It brings the resource graphs, process tables, and supporting pages together in one place, using real Mac measurements.

Changelog

• Added Processes, Performance, App history, Startup apps, Users, Details, Services, and Settings in a native Mac app.
• Added live CPU, memory, disk, network, and supported GPU views, including individual CPU-core graphs.
• Added sortable resource columns, search by name, process ID or user, process inspection, and guarded task controls.
• Added locally saved app history, pause and refresh controls, CSV export, keyboard navigation, and light/dark appearance.
• Corrected Apple Silicon process CPU timing and added observed per-process network traffic.
• Packaged a runnable Apple Silicon app for local use; this is not a public distribution release.
