pub fn render_usage_human(
cli: &UsageSummary,
guide: &TelemetrySummary,
) -> StringExpand description
Human decided usage output — the unified CLI + Guide read-back (ADR-046).
Two DIFFERENT error pluralizations by design: CLI rows use
error/errors ('s' if errors != 1), Guide rows always error(s);
both suffixes appear only when the count is nonzero, with the
tool/command column left-justified to 16 code points.
