Bringing uv and ty together

Astrally powered tools uv, Ruff, and ty are paving the way for an integrated Python development toolchain. The team has now released an experimental integration between uv and ty, allowing for enhanced support of Python scripts and a unified command for checks. By using inline metadata for dependencies, ty can now understand scripts and prepare environments using uv, enabling comprehensive type checking and editor features.

This integration is currently opt-in for PEP 723 scripts, but requires uv 0.12.3 or later and ty 0.0.76 or later. Over time, the team aims to make script support default and enable automatic environment setup for standard Python projects, as well as combine uv and ty capabilities for improved checks.
