Function: buildLookupWithKeyPayload()

function buildLookupWithKeyPayload(
   p2pDid, 
   selfHost, 
   selfPort, 
   dskKey
): Buffer;

Cloud-lookup payload — the CLASSIC variant (LOOKUP_WITH_KEY, 0xf126), reverse-engineered byte-exact against the app's own request (cold-start, phone force-stopped then reopened). Distinct from buildLookupWithKeyPayload2 (LOOKUP_WITH_KEY2, 0xf16a) which eufy-sdk already sent: that variant only ever got relay-pool candidates back for a remote (cross-WAN) target; THIS variant is what got the real app a genuine direct-device address.

[p2pDid:20][selfAddr:16][clientVersion:4 = 02 05 01 05][dskKey][0x00000000]. selfAddr is the caller's own observed LAN host:port (the socket's own bound address) — a STUN-like self-report, NOT the target's address. clientVersion was 02 05 01 05 in every capture; reproduced verbatim since its exact semantics (and whether it's validated) are unconfirmed.
