test(pty): detect markdown bold-bullet prose AUQs (fixes office-hours smoke)

office-hours auto-mode renders its mode question as `- **Building a startup**`
markdown bullets (office-hours/SKILL.md.tmpl:102) with no letter/number marker.
isProseAUQVisible only matched `A)`-style lettered or `1.`-style numbered
options, so the question went undetected: the model surfaced it at ~2m19s
(well under the 300s budget) but the harness kept scoring the run "working"
off the spinner glyphs and timed out — a false timeout on a question that was
already on screen.

Add Pattern 3: when an interrogative line ('?') is present AND 3+ bold-bullet
markers (`- **`) appear in the 4KB tail, classify as a prose AUQ. Bold is the
discriminator vs incidental prose bullets; the line anchor is dropped (stripAnsi
can collapse option lines) and the existing `❯ 1.` cursor gate still defers to a
live native list. Wires through the existing classifyVisible 'asked' path and the
timeout high-water-mark, so office-hours now classifies 'asked' instead of
'timeout'. Five unit cases: the office-hours render passes; no-'?', <3-bullet,
plain-bullet, and native-cursor cases stay false.
