ZenithSecureBytes class

A secure byte buffer that wraps a Uint8List and implements Zeroizable.

When zeroize is called (e.g. on scope disposal with purgeZeroize: true), all bytes in the underlying buffer are overwritten with 0x00. After zeroization, bytes returns a zero-filled view and isZeroized is true.

final token = ZenithSecureBytes(Uint8List.fromList([0xDE, 0xAD, 0xBE, 0xEF]));
userScope.container.getOrCreate(ZenithKey('token'), (_) => token);

manager.endScope('user_secure', purgeZeroize: true);

assert(token.isZeroized);                          // true
assert(token.bytes.every((b) => b == 0));          // true
