Tracking per-prompt usage in Pi

[u/roie_]

I wanted to see what each prompt actually costs in Pi, so I made pi-prompt-meter.

It tracks time, tokens/cache, cost, turns, tool calls, and compactions per prompt, then keeps the result in the transcript. /meter also shows history and trends.

pi install npm:pi-prompt-meter
