RtsPing
A map ping: a transient marker a player drops for communication (§HUD-1.2). Rides the deterministic command stream so every peer holds the same set, but is presentation-only — deliberately excluded from checksum() (§SEAM-4.1): a ping cannot affect any simulation outcome, and replays re-derive it from the recorded Ping command.
