PLIP was out of scope by design (Wi-Fi/HTTP-only); brought back in by
request. New src/scenario_now.{h,cpp}: owns the single esp_now recv
callback (no MSG_* demux needed — PLIP has no legacy ESP-NOW traffic),
reassembles scenario_mesh frames ({seq:u16 LE, total:u16 LE} + <=236 B
payload, <=64 KiB, 5 s sender-silence timeout) in a worker task, then
persists to LittleFS /scenario.json (temp-then-rename). Optional
consumer hook for a future Runtime 3 engine; stored-and-logged without
one. network_task calls scenario_now_init() once the station is up
(idempotent, repeated on reconnect).
Build green: pio run (devkit_es8388), RAM 14.8%, Flash 63.1%.
