scrypted: temp_c on the stats line; docs: triple-buffer model + window tuning

- Scrypted per-stream stats line gains temp=<c>C from /state temp_c —
  free thermal trending under streaming load.
- README Display strategy rewritten for the tear-free triple-buffer
  model: why the deferred fb-index reload tears under double
  buffering, why scan-tracked buffer roles beat vsync-waiting, and
  the tear_guard_engaged counter.
- New 'TCP window + EMAC tuning' section documenting the measured
  window raise, the EMAC-RX-pool-below-window RTO regression, and
  the pool >= TCP_WND invariant; stale 'window bump is safe but
  won't help' backlog text updated.
- Memory strategy updated (3 fbs, decoder writes into them directly,
  stream body ring).
