Add in-app Local Library PDF/eBook viewer

[Reza2kn]

Request

Add a first-party Local Library inside Command Center so users can upload and view their own offline PDFs, manuals, guidebooks, EPUBs, and MOBI/AZW files without relying on an external NAS or internet connection.

Proposed behavior

• upload/list/delete/download local library files
• view PDFs directly inside Command Center
• preview EPUB/text where lightweight extraction is available
• keep MOBI/AZW available for storage/download without overpromising preview support
• optionally index supported files into the existing Knowledge Base/RAG pipeline

Implementation PR

Implemented in PR #951.

Good news here, @Reza2kn: most of this is either already possible, in progress, or coming.

Uploading your own documents into the Knowledge Base already works today, and there's an open PR (#721, staged for an upcoming release) that adds in-app viewing, download, and metadata for stored files, which covers the core PDF/document case.

For a richer personal ebook library specifically (EPUB/MOBI/AZW with an in-browser reader and metadata), that's a great fit for our upcoming Supply Depot. It's a curated one-click app catalog, and Calibre-Web (a dedicated ebook library and reader) is one of the included apps. So rather than us building a second library viewer into Command Center, you'll be able to add a purpose-built one alongside NOMAD and point it at your collection.

Between KB upload, the #721 viewer work, and Calibre-Web via Supply Depot, the offline personal library you're describing is well covered. I'll close this as consolidated with those, and you can follow the roadmap for Supply Depot's release: https://roadmap.projectnomad.us

Thanks for the well-scoped writeup.
