fix: handle all-forward-slash paths in Windows cwd replacement

The cwd from template literals has mixed separators (backslash + forward),
but some tools (vitest) output all-forward-slash paths on Windows.
replacePathToken now tries all three forms: all-backslash, all-forward-slash,
and original mixed.
