feat: route Claude contexts to Person (P) entity type + auto-create entity dirs

Updates mintChittyId to explicitly request entity_type=P for context
minting, ensuring Claude sessions are Person (Synthetic) not Thing.
writeSessionBinding now auto-creates entity-scoped directories under
chittycontext/entities/{chittyId}/{project}/ on bind. Adds
detectProjectSlug helper for entity directory naming.
