Promote the internal test-only `UV_TEST_PYTHON_PATH` environment variable to a user-facing `UV_PYTHON_SEARCH_PATH` that overrides `PATH` for Python executable discovery. Add dedicated integration test coverage in `python_find_search_path`. https://claude.ai/code/session_01XUesSCJ1o1nHBxFEBEzfZ3

There was a problem hiding this comment.
Noticed this during review — I don't think we want this behavior so #19035 is needed.

Required for #19034 Arguably, we could keep our existing behavior and have `UV_PYTHON_SEARCH_PATH` implicitly disable the registry lookup, but I think that's too confusing. This disables registry lookups everywhere and modifications in `uv python install`. In the latter case, `UV_PYTHON_INSTALL_REGISTRY` takes precedence.
