Show HN: Pyra – a Python toolchain experiment inspired by uv and Bun

Serious question: what does Pyra do differently from uv? Both are Rust-based, both use pyproject.toml, both focus on determinism, and uv already owns mindshare here with Astral's funding behind it.

A "why not uv" section in the README would probably be the single highest-leverage thing you could add - otherwise every second commenter in this thread will ask the same question and the actual differentiator (if there is one) gets lost in noise
