Resolve conflicts in report-health: keep our richer fallback/trust model (telemetry_absent trust, snapshot fallback, finished/completed throughput) and adopt main's start-latency-unknown behavior so an absent measurement reports as unknown instead of a confident 0ms. renderMarkdown keeps our layout rewrite; main's compactFact change is covered by report-layout's metricValue. Adapt main's two render assertions to our current output.
