~anthropic/claude-sonnet-latest → A (6:4)

Side A fixes a real UI correctness bug (color mapped by score via min-max normalization instead of arbitrary list position) with clear rationale and thorough new unit tests validating the fix. Side B refactors a Deque to a Vec and removes the on-write trim/eviction logic in favor of a cap applied only at query time, which risks unbounded on-disk growth of vote history and is explained by only a terse, unclear commit message ('dequeue -> vec') despite touching more files.
