ipc: CmdSendMessage now routes to the named recipient only (m.SendTo) when
the "to" field is set, rather than broadcasting to all peers. Group messages
continue to use Broadcast. This is the correct privacy behaviour for DMs.
test-network.sh:
- Resolve each peer's hex id from get_state before joining the network,
using a retry loop with timeout to handle slow daemon startup.
- Added a DM section: alice→bob, bob→alice, charlie→alice, alice→charlie.
DMs use the "to" + "room":"dm:<peer_id>" convention.
- Fixed jq -cn (compact) instead of jq -n (pretty) so the IPC newline-
delimited protocol receives a single JSON line per command.
- pretty() now renders DMs as 📨 DM <from→to> rather than 💬 #room.
- Persistence check now breaks down totals by group vs DM message count.
