Special tokens can be user-defined. Numerous grammar fixes. Candidate tokens rendered for all token types.

Added

• Widget has dark mode (mainly for exporting).
• special_token function added for adding in <think> and similar.

Changed

• top_k exposed when echo=True for all token types (including fast-forward, inputs).
• Use greedy samplng if temp is smaller than 1e-5.

Fixed

• Normalized capture names not preserved, fixed.
• Logit array fix internally to avoid interfering mutations.
• top_k in widget is always 'unmasked' and not conditioned on mask.
