v1.1.0

Accuracy improvements measured by porting a 50-player shared world (kimu.nyc) onto Twinwire, plus everything in 1.0.1.

• Clock sync: a burst of pings after each connect (syncPings 8, syncPingMs 250, then pingMs 1000) instead of
  one a second after the first reply, and NetworkClock jumps to an estimate more than jumpMs (50) away instead of
  slewing for seconds. With 50 clients on an emulated 5G link, the spread of their server-time estimates had stayed at
  20 to 27 ms; every sample's timestamp carries that error, so it widened everyone's interpolation delay.
• AdaptivePlayback: lateness is a time-decayed histogram (2 ms buckets, halfLifeMs 2000) instead of the last
  128 observations, so its memory is a span of time: fed one observation per snapshot at 60 Hz it had forgotten a
  congested cell's stalls within two seconds and under-sized the delay. latenessMs exposes the covered percentile.
• Late states (endpoint.lateStates: 'deliver'): a state overtaken by a newer one on its stream is delivered once
  with late: true (within the last 32, de-duplicated; acks still follow the newest), so a 60 Hz snapshot stream with
  jitter fills its interpolation buffer instead of losing every reordered snapshot. Default unchanged ('drop').
• GameSession.flush() sends now instead of at the next 60 Hz pump. sendEvent, broadcast and Room.send accept
  typed interfaces (JsonInput), still checked when serialized.
• Impairment: stallMs stalls the WebSocket the way a retransmitted TCP segment does: with probability loss, a
  send and everything queued behind it waits stallMs longer, in order (stats.impairedStalls). Without it, loss
  still drops datagrams only. This makes a lossy cellular network comparable across the two wires in load tests.
