"""
Validate MeshCore Bot config.ini section names.

Run standalone: python validate_config.py [--config config.ini]
Exits with 1 if any errors are found, 0 otherwise. Warnings and info are printed but do not affect exit code.

Use --strict to also fail on "Unknown section" info messages. This is intended for
CI checks against the shipped example configs (config.ini.example, etc.), which should
never contain a section outside the canonical list (see CANONICAL_NON_COMMAND_SECTIONS
in modules/config_validation.py). It is not recommended for validating end-user configs,
since those may legitimately contain sections for local/third-party plugins.
