DebugInputInjectionSystem (#if UNITY_EDITOR) gains FireSocket(i, frames) + per-socket hold
frames + the OnUpdate socket-event sets, mirroring the legacy Fire injection. Drives the real
gather->command->prediction->AbilityFireSystem path per socket for headless validation.
Used to validate group-A live (instant-play ServerWorld+ClientWorld): socket 0&1 = a projectile
Spark, injected same-frame -> maxSrvProj=2, maxCliProj=2 (server==client parity),
distinctSpawnIds=2 with distinctSocketBits=2 (the SpawnId desync fix confirmed LIVE), both
per-socket cooldowns advanced. Netcode half of the group-A gate: PASS.
