Description

Summary

The new --active flag (#11189) is a great addition and I think it goes some way to allow uv and pyenv to work better together (see #6204).

Would it be possible to add a new environment variable to make that flag the default? For example, the PR suggested something like UV_PROJECT_ENVIRONMENT=ACTIVE but could also be UV_ACTIVE=1. Or maybe this already works? If so, it's not clear from the documentation.

Contributor guide

Research direction
Examine uv’s environment variable handling code, find where flags are mapped, and add a new env var to enable the active flag by default.
