Add out-of-order segment reassembly (#148)

* feat(tcp): add out-of-order segment reassembly Add an opt-in, bounded out-of-order reassembly buffer so a single lost segment can be recovered by retransmitting the gap while later segments are held and delivered once the gap fills. The receiver also subtracts buffered out-of-order bytes from the advertised receive window and avoids challenge-ACK aborts for in-window future data. Reassembly is disabled by default. Generated with LLM assistance.
