fix: Revert pytest hook parameter names to match hookspec

- Changed _item back to item in pytest_runtest_teardown
- Changed _session back to session in pytest_sessionfinish
- Pytest hooks require exact parameter names matching the hookspec
- Cannot use underscore prefix for unused parameters in hooks
- Fixes PluginValidationError when running pytest with --testiq-output
- All tests passing (190/190)
