class MessageDropCalculator

Calculates if any messages were not received by a subscriber (e.g. dropped)

Two update paths:

• registerReceivedMessage(seq): real messages — always counts missing IDs after the first.

• applyReceivedPublisherUpdate(seq): heartbeats — counts all missing IDs only if no real messages arrived since the last external update.

Not thread-safe
