Interaction between two fixes in this series. The host now tells the client when a rebuild re-resolves an Automatic rate, and that rate can legitimately sit ABOVE the client's climb ceiling — the ceiling is the negotiated start rate until the capacity probe raises it, while the host's re-resolve answers "what do these pixels actually need" (a 1080p session mirroring a 4K panel resolves ~3× higher). Left alone, the client would learn the new rate, notice it was above a stale ceiling, and step the host straight back down off the rate it had just chosen for itself. So an ack raises the ceiling to meet it. `set_ceiling` only ever raises and still clamps to PUNKTFUNK_ABR_MAX_MBPS, which is the one limit that should bind here. No effect on ordinary acks: a climb is never requested above the effective ceiling to begin with.
