fix: (scaffold) suppress the duplicate look after a Telly on-tick raw send

In OnTick/OnTickSnap, the raw C06 (dispatched before the C08 place so the server raytraces the right rotation) and the same-tick movement packet both carried the identical rotation -> GrimAC AimDuplicateLook (from==to). Expose a lastReported accessor on EntityPlayerSP (new IMixinEntityPlayerSP) and, right after each raw send, sync the client's last-reported look to it; the follow-up movement packet then computes zero rotation delta and emits a position-only update (C04) instead of re-sending an identical look. Preserves the place-before-move ordering.
