Show HN: Slivingdoc, conflict-resolving notebook for agents w. S3 backend

Agents needs to store context, and share context. We haven't yet figured out how to do muli-agent swarms in a good way, but letting agents synchronize durably seems to be a key point, a problem which needs a solution regardless. So I decided to separate the concerns and tackle this bit before trying to build a swarm.

Slivingdoc is git + s3 combined into a "hot path". Conflict resolution via git, persistent storage + backup via s3. Agents + humans see gitlike-semantics, without needing to worry about the complexities. See website above for details.

Intended to be run as cli or mcp server (stdio).
