fix(bundle): v0.6.0 version drift + ruff target-version

- src/sin_code_bundle/__init__.py: bump __version__ 0.2.0 → 0.6.0
  (was stale since pre-v0.4.0, consistency check now passes)
- pyproject.toml: tool.ruff.target-version was '0.5.1' (invalid),
  should be 'py311' — ruff couldn't parse pyproject.toml at all
