fix: MCD-1295 Declare minimatch as a runtime dependency.

[drubot]

minimatch is imported at runtime in src/runtime/server/utils/generateComponentIndex.ts (bundled into dist/module.mjs, executed during nuxt prepare), but was only declared in devDependencies. Consumers therefore resolve whatever minimatch happens to be hoisted to their top-level node_modules/ — a phantom dependency.

When the hoisted copy is minimatch ≤5 (CJS-only, no named export), nuxt prepare fails with:

[error] Named export 'minimatch' not found. The requested module 'minimatch' is a
CommonJS module, which may not support all module.exports as named exports.
  at async Array.<anonymous> (node_modules/nuxt-component-preview/dist/module.mjs:141:44)

Moving minimatch from devDependencies to dependencies guarantees an ESM-capable ≥10 copy resolves for the module's import.
