test(cli): normalize path comparison in set-local test for Windows

set-local stores `path` via Path(...).as_posix() (matching bm project add
and the rest of the codebase, which keep paths as POSIX strings). The
test compared against str(Path), which on Windows produces backslashes
and fails the equality check on the Windows CI runner.

Use .as_posix() in the assertion so the test matches what the production
code actually writes to config.
