Streams transmissions + observations from SQLite at startup into
5 indexed in-memory structures. QueryPackets and QueryGroupedPackets
now serve from RAM (<10ms) instead of hitting SQLite (2.3s).
- store.go: PacketStore with byHash, byTxID, byObsID, byObserver, byNode indexes
- main.go: create + load store at startup
- routes.go: dispatch to store for packet/stats endpoints
- websocket.go: poller ingests new transmissions into store
