LANTERN P1 step 6: manual-aim windups (SoD readable telegraphs)

AbilityDefBlob/AbilityDefinition gain WindupTicks. AbilityFireSystem's socket
loop resolves each socket at the historical command (serverTick - WindupTicks)
via GetDataAtTick — a pure fn of replicated data on both worlds (Build Spec §4/
DB-6: no local fireAtTick that would diverge under reprediction; fireCount from
that command, spawn uses the current tick's aim/pos; history gap = no-fire).
WindupTicks set on the 4 non-Blink Sparks (Blink is movement, resolved by
BlinkSystem). 497 EditMode green (no regression). Client telegraph VFX + the
reprediction L3 test are operator-eyes / netcode-world follow-ups.
