ruff(fix) Move A002 suppression to per-file-ignores in pyproject.toml

why: The old `# ruff: NOQA: A002` file-level comment syntax is no
longer recognized by ruff (RUF103), causing CI to fail.

what:
- Remove obsolete `# ruff: NOQA: A002` from subprocess.py
- Add per-file-ignores entry in pyproject.toml for A002 on subprocess.py
