tools/trace_digest.py reads an APS5_TRACE_FRAMES capture (aps5-trace-*.json.gz)
and prints a markdown report of a few KB, or the same data as JSON: the
summary line from aps5-summary.jsonl, the slowest frames with their largest
slices, the busy, wait and untraced time of each thread, the largest slices
per frame, the longest waits, and with --stacks the hottest frames of an
APS5_SAMPLE_WORKER collapsed-stack file. Python standard library only; a
unittest checks every section on a small synthetic trace.
