libSceNKWebKitRequirements technical debt

133 pending exports in Export.cpp are present in the PS5-3.20_Libs inventory. Their prototypes and behavior are unverified. They use the no-parameter import-resolution convention and throw through NotImplemented_nid_no_patch; these declarations make no ABI or behavior claim.

Additional callable exports - 32 entries present in both version-labelled images are import-resolution declarations only. Neither label independently authenticates retail firmware provenance. These NIDs are absent from the pinned public 3.20 catalogue. 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.
