`codegraph query` printed `(score * 100)%` next to each hit, but `score`
is an unbounded BM25/FTS relevance magnitude (relative-ranking only), so
it rendered as values like "12042%" that made the output look broken.
Results already arrive in rank order, so drop the score from the
human-readable output entirely — matching the MCP search tool, which
shows no score. The raw `score` stays in `--json` for programmatic
sorting/thresholding. Also corrects the SearchResult.score doc comment,
which wrongly claimed a 0-1 range. Adds an end-to-end regression test.
