~anthropic/claude-sonnet-latest → A (3:2)

Side A eliminates ~1800 lines of an overengineered, unreliable keystroke-transition graph parser and replaces it with a much simpler, testable URL-extraction function plus a paste-and-go UI, removing significant tech debt and a whole class of race-condition bugs (also dropping the now-obsolete Playwright race test). Side B is a solid, well-tested correctness fix (enforcing vote ratio bounds across DSL/UI/reducer) but is narrower in scope and impact than A's architectural simplification.
