taohong-oai 79dcb11c90 Track automatic review overhead in critical-path durations (#59251) ...

## What changed

Add `ReviewExecution` observers and an optional `auto_review_overhead` subcomponent to `PathDurations`. Compute overhead by subtracting the union of observed child execution intervals from automatic review time, clipping intervals to the selected path segments and requested window.

Track concurrent and retried submissions, preserve unknown attribution for incomplete or unobserved execution, and allow observations to be sealed against late callbacks.

## Testing

Add unit coverage for overlapping execution, window clipping, human waits, cached reviews, losing parallel paths, canceled submissions, and sealed observations.
