you d8d0572abb perf: in-memory packet store — all reads from RAM, SQLite write-only
- PacketStore loads all packets into memory on startup (~11MB for 27K packets)
- Indexed by id, hash, observer, and node pubkey for fast lookups
- /api/packets, /api/packets/timestamps, /api/packets/:id all served from RAM
- MQTT ingest writes to both RAM + SQLite
- Configurable maxMemoryMB (default 1024MB) in config.json packetStore section
- groupByHash queries computed in-memory
- Packet store stats exposed in /api/perf
- Expected: /api/packets goes from 77ms to <1ms
