- #120323: apply_scratch_tmp_env: Git Bash TMPDIR=/tmp prevents the scratch dir from being exported on Windows
- PR #120335: fix(scratch): keep Git Bash temp files in managed scratch

These items address a problem where Git Bash sets TMPDIR to the MSYS pseudo-path /tmp, interfering with the scratch directory export on Windows. The work involves detecting and overriding that default so the scratch directory behaves correctly in Windows shell environments.

## TL;DR
