libSceVideoNativeExtEssential technical debt

Native video export iwAQhvb9BvY is a function record with qualifier K#A in older and later version-labelled modules. Both map library ID 10 and module ID 0 to libSceVideoNativeExtEssential. Older module words: 0x08540001, 0x03200004; later: 0x13590001, 0x13600007. Both contain six function NIDs; sorted-LF SHA-256: 2c1bdced348433c9cb792b70a0f043d932e6f822157250d5256bb46c8867bd86, using the static ELF membership procedure. Labels do not authenticate retail provenance; the digest identifies the NID set only. Independent verification requires a matching image. The export name, signature and behavior are unverified; this declaration throws.

sceVideoNativeExtEssential_CreateDecInstance, sceVideoNativeExtEssential_DestroyDecInstance, sceVideoNativeExtEssential_Finalize, sceVideoNativeExtEssential_Initialize and sceVideoNativeExtEssential_IsInit (libSceVideoNativeExtEssential) - names and NIDs are present in the PS5 3.20 export inventory, but no credible prototypes were found. The declarations have no parameters solely to resolve known imports; this is not an ABI claim and callers must not call them until signatures are verified
