Updated TTFAMetricsData documentation to reflect the breakdown fields added in pipecat-ai/pipecat#4814: - Renamed `value` field to `ttfa` in field reference table - Added `ttfb` and `leading_silence` fields to show latency breakdown - Updated example code to demonstrate accessing all three fields - Clarified that `ttfb` mirrors the standalone TTFBMetricsData The breakdown allows consumers to see how much perceived latency is silence padding without correlating separate metrics events.
