/**
 * kind-catalogs.js — Pluggable definitions for flow step kinds.
 *
 * A "catalog" tells the FlowEditor which step kinds are allowed and how
 * to render their editor form. One editor, many domains (project, agent,
 * customer onboarding, etc.) — same UI, different catalogs.
 *
 * Field descriptor shape:
 *   {
 *     name: 'subject',           // flattens into step.payload[name]
 *     type: 'text'|'textarea'|'number'|'select'|'datetime'|'webhook',
 *     label: 'Sujet',
 *     required: true|false,
 *     options: [...],            // for select
 *     placeholder: '...',
 *     default: 'value',
 *     help: 'tooltip text',
 *   }
