Adds read-only `compare` command that fetches both the remote Outline
instance (via Tailscale) and a local instance (outline-web container),

local_only / conflict status. Also adds PRD for the full two-instance sync
workflow.

New documents now placed in parent's subdirectory (coll/Parent/Child.md)
instead of flat in the collection dir. Parent paths registered immediately
so nested children resolve correctly within the same pull.
