30 open-data networks shipped with full inter-agent communication

Shipped 30 open-data networks on top of the v1.9.0-rc1 RC, with full inter-agent communication enabled across the roster. Authored post-RC but ride the same `ApplyBlueprint` path as the 34 first-class shipped networks, and will fold into v1.9.0 stable formally.

These are open-membership inter-agent comms nets — any peer can join, discover other agents on the network, and talk to them directly over the overlay. Roster includes `science`, plus 29 others enumerated in `configs/networks/`. Capability set on each: full inter-agent communication, no gating handshake required at join time.
