* test(rsi): cover period/value accessors, name, naive flat-series branch
Codecov flagged 7 lines in indicators/rsi.rs (file at 96.42%): const
accessors period (60-62), value (65-67), Indicator-impl name (145-147),
and line 167 in the test-helper rsi_naive's ag==0 fallback. The
proptest reference never lands on a fully flat series so the helper's
50.0 branch was dead.
Add accessors_and_metadata covering period/value/name and
naive_helper_flat_series_yields_50 driving rsi_naive on [42.0; 20] —
both avg_gain and avg_loss converge to 0, hitting the 50.0 branch.
rsi.rs now at 196/196.
