mtop 1.2.0

A few new things.

mtop compare "<prompt>" model1 model2 runs the same prompt past a few ollama models one at a time and prints tok/s side by side, fastest first. Handy for deciding whether the bigger model is worth the wait.

-notify pops a desktop notification the first time a GPU crosses the alert line (high memory or temperature). No new dependencies, it just uses whatever the OS already ships: osascript on a Mac, notify-send on Linux, a powershell toast on Windows.

-history keeps recent requests in ~/.mtop/history.jsonl and reads them back on the next run, so the stats panes aren't empty after a restart.

On Apple Silicon, running mtop with sudo now gets you real GPU utilization from powermetrics, on top of the memory figure you already had.

The GPU pane shows how much VRAM the loaded models account for, and /metrics now includes the GPU gauges, not just the request counters.
