feat: upgrade stream cipher from XOR to AES-128-CTR

Browse Source 
Replace the XOR obfuscation cipher with AES-128-CTR using the Windows
BCrypt API. Key material grows from 16 to 32 bytes (16 AES key + 16 IV).
All callers auto-adjust via StreamCipher::KEY_SIZE. No handshake or
protocol changes needed beyond the larger MC|CKey payload.
