H1K0 f00a6c1b3a feat: add bigram repetition penalty to generate_period ...

Tracks ROOT-level bigrams (prev_root → curr_root) across chord-change events.
At each FREE position, subtracts penalty * count(prev→root) from ROOT logits,
capped at 3.0 to prevent NC/HOLD flooding at extreme values.

Practical range: 0.5 (mild, breaks loops after 2 occurrences) to 1.0
(aggressive). Default 0.0 keeps backward compatibility.

Added --repetition-penalty flag to scripts/generate.py.
