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

Side B fixes a real display/URL-encoding bug (hrefs now use display_path instead of raw storage path) and strengthens a browser test to exhaustively vote all 45 pairs and assert correct ranking output, adding real verification value. Side A mostly deletes a large, elaborate but unused keystroke-autocomplete parser and replaces it with a much simpler paste-and-go flow, which is a reasonable simplification but is largely destructive/refactor churn rather than a new correctness fix, and also removes a nontrivial regression test (parser_race.clj) without a clear replacement guard for the same race condition.
