libSceNpSessionSignaling technical debt

sceNpSessionSignalingGetConnectionStatus (libSceNpSessionSignaling) - (int32 context id, int32 connection id, int32* status, SceNetInAddr* peer address, uint16* peer port) is ASTRO BOT's (PPSA21564 01.007.000) call at 0x30622B: the context id from a 32-bit field, the connection id, three stack outputs, a negative result taken as an error, then the address passed to sceNetInetNtop(AF_INET, ...) and the port to sceNetNtohs. It matches PS4's sceNpSignalingGetConnectionStatus. The title reaches it only for a connection id from the signaling library, which offline never hands one out. No session ever activates offline, so every connection id answers CONN_NOT_FOUND (0x8055330C, from shadPS4) without writing the outputs, and a null status answers INVALID_ARGUMENT. The context id is not checked, as contexts are not tracked. The console's answer for an unknown context or connection is unverified
sceNpSessionSignalingCreateJoinActivate, sceNpSessionSignalingGetConnectionFromNetAddress, sceNpSessionSignalingGetCustomProperty, sceNpSessionSignalingGetGroupFromPeerAddress, sceNpSessionSignalingInitializeWithPort, sceNpSessionSignalingJoinActivate and sceNpSessionSignalingSetCustomProperty (libSceNpSessionSignaling) - names and NIDs are present in the PS5 3.20 export inventory, but no credible prototypes were found. They are declared without parameters solely to resolve known imports; this is not an ABI claim.
