Why must ProcessHider be compiled as a 32-bit application?

ProcessHider must be compiled as 32-bit because it includes code to identify and inject into both 32-bit and 64-bit processes. On 64-bit systems, it spawns a 64-bit daemon (x64Hider.exe) to inject 64-bit payloads, but the main binary's compatibility relies on being 32-bit. This design ensures all target processes can be hooked regardless of bitness.
