Expand description
Handler for the normalize-entities CLI subcommand (GAP-15).
Scans all existing entity names in the namespace and normalizes them to
kebab-case ASCII using crate::parsers::normalize_entity_name.
When a normalized name already exists (collision), the source entity is
merged into the target using the same logic as merge-entities:
relationships are retargeted via UPDATE OR IGNORE + DELETE, then
the source row is removed. Otherwise the entity name is updated in place.
