test_root_resolves_to_project_schematic created its project directly in
tmp_path, where the autouse _set_test_search_paths fixture also drops a
test_project.kicad_pro. With two .kicad_pro files in one directory,
_resolve_root_schematic returns whichever os.listdir yields first — myproject
on ext4, test_project on APFS — so the test passed on Linux and failed on macOS.
Anchor the test's project in its own subdirectory so the root walk finds this
project's .kicad_pro and stops before reaching the sibling. Product code is
unchanged and correct; this was test isolation only.
