Review Comment:
Returning the internal byte array directly allows external modification of
the StringId's state. Consider returning a defensive copy with `return
this.bytes.clone();` to maintain immutability.
```suggestion
return this.bytes.clone();
```

Review Comment:
Similar to the compareTo method, this optimization may not be effective
since `other.asString()` and `other.asBytes()` will trigger conversions if the
other StringId doesn't have the required representation. Consider optimizing
for cases where both objects have the same representation type.

Review Comment:
This optimization to avoid string conversion during comparison may not be
effective since `other.asBytes()` will still trigger encoding if the other
StringId only has a string representation. Consider checking if both objects
have bytes available before using byte comparison.
