- ui/Dockerfile: copy package-lock.json and run npm ci --omit=dev in the
runtime stage so marked (and other runtime deps) are available to
adapter-node at startup — fixes ERR_MODULE_NOT_FOUND for 'marked'
- storage: add ReindexChapters to Store interface and HybridStore — walks
MinIO objects for a slug, reads chapter titles, upserts chapters_idx
- server: add POST /api/reindex/{slug} to rebuild chapters_idx from MinIO
