- PolicyIntegrityManager calculates and persists policy directory hashes.
- Config integrates integrity checks during startup.
- PolicyUpdateDialog prompts users in interactive mode.
- --accept-changed-policies flag supports non-interactive workflows.
- toml-loader refactored to expose file reading logic.
