Describe the bug

The docstring for MCTS.run() states the return dictionary contains two keys: candidate and score. However, the actual return value includes a third key, sequence, which is undocumented.

Relevant code:

• pyaptamer/mcts/_algorithm.py

Docstring (lines 268–270):

Returns
-------
dict
    Dictionary containing the final candidate sequence (`candidate`) and its
    score (`score`).

Actual return (lines 312–316):

return {
    "candidate": reconstructed_candidate,
    "sequence": self.candidate,
    "score": self.experiment.evaluate(reconstructed_candidate),
}

Expected behavior

The docstring should document all three keys:

Returns
-------
dict
    Dictionary containing the reconstructed candidate sequence (`candidate`),
    the raw encoded sequence (`sequence`), and its score (`score`).
