/**
 * Diagnostics tools — mirrors routes/diagnostics.ts. Pure read-only.
 *
 * Three tools:
 *   diagnose_job            — per-job verdict (compact by default; opt into events/streams)
 *   find_stalled_jobs       — fleet-level: running jobs with no recent status change
 *   find_orphaned_signals   — fleet-level: suspended waiters with no escalation row
 *
 * Efficient usage: start fleet-wide (find_orphaned_signals for the genuinely
 * broken case, find_stalled_jobs for candidates), then call diagnose_job on a
 * specific id for root cause — do not fan diagnose_job across every job.
 * diagnose_job returns the verdict only by default; add include: ['events'] or
 * ['streams'] for the heavy arrays. For full raw message payloads, use the
 * stream browser (list_stream_messages filtered by jid).
