Pull request overview

Updates benchmark result renderers to avoid displaying misleading 0.00s timing values when a provider has 0 successful iterations, showing -- instead.

Changes:

• README HTML table: render -- for Median/P95/P99 TTI when ok === 0.
• Sandbox SVG: render -- for Median/P95/P99 and force “slow” coloring when ok === 0.
• Storage SVG: render -- for Download/Throughput/Upload and force “slow” coloring when ok === 0.
• Sandbox CLI table: render -- for Median/P95/P99 columns when successful === 0.
