Use exact decorated symbol names verified against Minecraft.Client.pdb

Verified all hook targets exist in the compiled game's PDB:
- ?MinecraftWorld_RunStaticCtors@@YAXXZ
- ?tick@Minecraft@@QEAAX_N0@Z
- ?init@Minecraft@@QEAAXXZ
- ?ExitGame@CConsoleMinecraftApp@@UEAAXXZ (replaces destroy which is inlined)

Minecraft::destroy/run_end/stop are not public symbols (likely inlined),
so the shutdown hook now targets CConsoleMinecraftApp::ExitGame instead.
