Subject: [PATCH v2] t4200: convert test -[df] checks to test_path_* helpers

From: PRASHANT S BISHT <[email-masked]>
Date: Mon, 16 Mar 2026 22:54:57 +0530

Replace old-style path existence checks in t4200-rerere.sh with
the appropriate test_path_* helper functions. These helpers provide
clearer diagnostic messages on failure than the raw shell test
builtin.
