jack 2fed4b7c31 Fix XChaCha20 tests to avoid Swift Testing crash 
The original tests using in-place Data modification with `data[0] ^= 0xFF`
caused signal 5 crashes during parallel test execution. Fixed by:
- Using `import struct Foundation.Data` for efficiency
- Converting Data to byte array before modification to avoid the crash
- Simplified error-throwing tests to use boolean flags instead of
  complex error type matching

jack b956e407ff Add unit tests for XChaCha20Poly1305Compat error handling 
15 tests covering:
- Valid input roundtrip (seal/open with and without AAD)
- Different nonces produce different ciphertext
- Invalid key length throws error (short, long, empty)
- Invalid nonce length throws error (short, long, empty)
- Error details contain expected/got values
- Authentication fails with wrong key
- Authentication fails with tampered ciphertext
