"""Round-trip tests for organization config schema.

Covers:
- save() writes schema_version: 2 org config under company_orgs/
- load() rejects schema_version > 1 with ValueError
- Export YAML round-trips roles/employees bitwise identical

All tests redirect _find_project_root to tmp_path so the real config is untouched.
