ulobjmgr technical debt

ulobjmgr registers no object: _sceUlobjmgrRegisterObject always hands out id 0 and _sceUlobjmgrUnregisterObject releases nothing, as shadPS4 does

_sceUlobjmgrRegisterObject (ulobjmgr) - parameters taken from shadPS4 (PS4): a nonzero 64-bit object, a nonzero 32-bit kind and a 32-bit id output; the meaning of the first two and the PS5 signature are unverified. The id bound of _sceUlobjmgrUnregisterObject (below 0x4000) and the raw EINVAL (22) return also come from shadPS4

Additional callable exports - 2 entries observed in the 3.20 export inventory and present in the later 13.60-labelled inventory are import-resolution declarations only. The later inventory label does not authenticate a retail firmware version. Parameter lists, return types and behavior are unverified; parameterless int declarations are placeholders, not verified ABI contracts. Every entry throws through NotImplemented_nid_no_patch. Unidentified names use literal NID aliases. No runtime functionality is implemented. Data exports require separate layout and ownership analysis. Identified candidate names match their NIDs in the public symbol database or supplemental catalog.
