feat: v0.3.0 — State, Memory, message_status, MCP instructions
Phase B + C + message delivery status.

State: shared key-value store per mesh. set_state pushes changes
to all peers. get_state/list_state for reads. Peers coordinate
through shared facts instead of messages.

Memory: persistent knowledge with full-text search (tsvector).
remember/recall/forget. New peers recall context from past sessions.

message_status: check delivery status with per-recipient detail
(delivered/held/disconnected).

Multicast fix: broadcast and @group messages now push directly to
all connected peers instead of racing through queue drain.

MCP instructions: dynamic identity injection (name, groups, role),
comprehensive tool reference, group coordination guide.
