Add public accessor for the challenge hash component of ML-DSA signatures, needed by hybrid schemes that share the challenge across both classical and post-quantum components.

Hello!
Would be nice to have a public getter for c_tilde since it's a public component per FIPS 204.
Some implementations need direct access to it and encoding the whole signature just to grab it feels overkill.
Let me know what you think and have a nice day!
