MSG_MHF_GET_EXTRA_INFO (0xA6) and MSG_MHF_GET_COG_INFO (0xC3) had Parse() returning NOT IMPLEMENTED. The dispatch loop treats any Parse error as a hard drop — no ACK is ever sent, so the client waits indefinitely and effectively soft-locks when entering the G-rank Workshop or Master Felyne (Cog) screens. Fix: parse AckHandle (the only field we can confirm from the protocol) and respond with doAckBufFail so the client receives a well-formed buf-type ACK with error code 1. The client's fail branch for these requests exits cleanly without reading response fields, avoiding the read-past-EOF crash that an empty success ACK would cause. The full response format for both packets is still unknown; a complete implementation requires further RE. The TODO comments mark the gap. Fixes #180.
