Pre-landing review fixes for GST-135: readMergedPrs, readGateRuns and readReleases throw past MAX_PAGES
instead of returning a partial count; readReleases pages until it reaches the window start;
listWorkflowRuns compares both bounds with Date.parse and skips unparsable timestamps; tests for a
sub-second window, releases behind a full page and the PR page cap; doc wording on the red-train row
and the unverified 142-PR baseline removed.
