A no-cap crawl could take many seconds with no feedback. Wires the
existing aborist.progress.Progress into both phases so stderr shows
heartbeats every 2s (Progress's default interval).
Discovery phase: prints prefix='crawl', counts discovered URLs,
shows queue depth as the secondary number ('inserted' slot in the
Progress format — works fine, semantically "still to do").
Ingest phase: prefix='ingest', total_estimate=len(urls) so the user
sees percent + ETA. Threads through ingest_source's existing
progress= parameter.
Plus three banner lines to stderr at phase boundaries (start crawl,
end discovery, start ingest) so even sub-2s crawls show signs of
life. All flushed via Progress's flush=True path; stderr is
line-buffered by default so this works without PYTHONUNBUFFERED.
Tests stay green (Progress goes to stderr, pytest captures only the
stdout summary). 19 bridge tests + 273 default suite, all passing.
