build_exe.py now runs compile -> link (+ .map) -> patch. scripts/exe/postprocess.py
applies scripts/exe/patches/NNNN_*.py in order, each located by symbol, verified
against exact bytes, dropping base relocations it overwrites; --no-postprocess skips it.
0001: CSession::LoadExternalSettings jumps over switch (g_serviceType) to case 0,
as the original does at 0x00DFD08F (e9 10 00 00 00).
