Subject: [PATCH] Match Net::USERHandler::update()

100% byte-match (relax-reloc) for the update method declared in USER.hpp.

The function checks NetManager::hasFoundMatch() and dispatches to internal
helpers fn_1_152498/fn_1_152B08 (still unmatched, declared extern "C" so
the asm fallback resolves them).

Verified:
- objdiff-cli with -x flag: 100% match
- Full build still produces correct main.dol/StaticR.rel sha1
