Safe evasion techniques working - libphotoshop_packed_safe2.dll functional

Working features confirmed:
- High BSS modification (increased .text section size)
- Modified import order (LoadLibraryA, GetProcAddress, VirtualProtect, ExitProcess)
- Enhanced dummy imports (GetCurrentProcess, GetTickCount, QueryPerformanceCounter, GetModuleHandleA)
- Section flag modifications to break UPX patterns
- UPX string removal (changed to 'PACK')
- Modified timestamp (0x12345678)

Ready for additional evasion techniques based on should_evade.txt analysis.
