/**
 * Field Kit Plugin for EmDash CMS
 *
 * Provides composable field widgets for `json` fields configured entirely
 * through seed options — no React code required from site builders.
 *
 * Ships four widgets:
 *   - object-form — inline form for flat JSON objects
 *   - list        — ordered array editor with add/remove/reorder
 *   - grid        — rows × columns matrix with configurable cell type
 *   - tags        — free-form tag/chip input for string arrays
 *
 * Usage in astro.config.mjs:
 *   import { fieldKitPlugin } from "@emdash-cms/plugin-field-kit";
 *   emdash({ plugins: [fieldKitPlugin()] });
 *
 * Usage in a seed field:
 *   {
 *     "slug": "ingredients",
 *     "type": "json",
 *     "widget": "field-kit:list",
 *     "options": { "fields": [...], "summary": "{{name}}" }
 *   }
