LinXiv v0.5.0: Headless research-DB image with iroh for self-hosting

I am making a lot of progress on the headless research-DB node designed to be somewhat premade for a research group wanting to aggregate their research corpus and knowledge base. Lots to work on but excited to show what I have so far. Biggest adds besides headless node, CRDT journal via Automerge, knowledge graph performance improvements.
