Closes #24786

Summary

Ruff cache files used unix default 0600, which prevented shared-cache setups from working as expected. This copies uv’s approach that Micha mentioned in the issue by creating cache temp files with 0666 before umask, so they behave like normal files.

Test Plan

Added unix test, also created a manual script and tested locally.
