// CustomAttributeDefinition defines a custom attribute schema for conversations or contacts.
// Reference: Chatwoot app/models/custom_attribute_definition.rb
// Account-scoped: each definition belongs to an account and applies to either
// conversation or contact models (attribute_model field).
//
// Chatwoot compatibility notes:
//   - JSON uses "attribute_key" (Chatwoot name) as alias for attribute_name
//   - JSON uses "attribute_display_type" (Chatwoot name) as alias for attribute_type
//   - JSON uses "attribute_description" (Chatwoot name) as alias for description
//   - attribute_values stores predefined options for list-type attributes
//   - regex_pattern / regex_cue provide input validation beyond type checking
