DRY (Don’t Repeat Yourself) penalty. Ported from llama.cpp PR #9702.

Uses suffix matching to find the longest repeated sequence ending at the current position in the token history. For each candidate token, checks if appending it would extend a previously-seen sequence. Applies exponential penalty: penalty = multiplier * base^(match_length - allowed_length)

Sequence breakers (e.g., newlines, quotes, braces) reset tracking, preventing false positives in structured output like JSON tool calls.
