描述

Description

refresh of #1775

Could we add support for an environment variable to override some hard coded url's in Hatch? (from https://docs.astral.sh/uv/configuration/environment/) ?

This could help with https://github.com/pypa/hatch/issues/1596

The use case is within #1596 , where Python distributed binaries are pulled from 'https://github.com/indygreg/python-build-standalone/releases/download/' . I would like to override this URL for one relevant to my environment. Note: this is an old request and perhaps something got changed since the initial request.

研究方向
The issue requests adding an environment variable to override hardcoded URLs for Python distribution downloads, similar to UV's configuration. Key files to investigate include Hatch's configuration loading (likely in `src/hatch/env.py` or similar) and the URL constants in the `python` distribution module. Refer to the closed issue #1775 and the related issue #1596 for context. The implementation should follow existing patterns for environment variable overrides (e.g., using `os.environ.get()`).
