Implement secure AES-CBC encryption with external C++ decryption

Browse Source 
- Replace weak ECB encryption with AES-128-CBC + PKCS7 padding
- Implement secure key derivation: SHA256(password + salt)
- Add cryptographically secure random IV generation
- Create standalone C++ decryptor for external binary decryption
- Update stub to require external decryption workflow
- Maintain cross-platform compatibility (Linux/Windows)
- Add proper error handling and padding validation

Security improvements:
- AES-128-CBC instead of ECB (prevents pattern analysis)
- Random IVs prevent identical plaintext producing identical ciphertext
- Password-based key derivation with salt
- PKCS7 padding with validation
- External decryption prevents embedded keys
