Add cross-platform x86 emulation via Unicorn Engine

Solves Linux execution limitation without Wine!

New Component: WardenEmulator
- Uses Unicorn Engine to emulate x86 CPU on any platform
- Can execute Windows Warden modules on Linux/macOS/ARM
- Provides sandboxed execution environment
- Intercepts Windows API calls with custom implementations

Features:
- CPU: x86 32-bit emulation via Unicorn
- Memory: Emulated address space (1MB stack, 16MB heap)
- API Hooks: VirtualAlloc, GetTickCount, ReadProcessMemory, etc.
- Safety: Module runs in isolated emulated environment
- Cross-platform: Works on Linux/macOS/Windows/ARM hosts

Architecture:
- Module code loaded into emulated memory at 0x400000
- Stack at 0x100000 (1MB)
- Heap at 0x200000 (16MB)
- API stubs at 0x70000000 (high memory)
- Intercept and provide Windows API implementations

Benefits vs Wine:
✓ Lightweight (no full Windows compatibility layer)
✓ Sandboxed (module can't harm host system)
✓ Cross-architecture (works on ARM, RISC-V, etc.)
✓ Full control over execution (can inspect/modify state)
✓ Easier debugging and analysis

Build:
- Added libunicorn-dev dependency
- Conditional compilation (HAVE_UNICORN)
- Falls back gracefully if Unicorn not available

Status: Infrastructure complete, ready for integration
Next: Connect WardenEmulator to WardenModule for real execution

Note: RSA modulus extraction script added but needs refinement
(current candidates are x86 code, not data section)
