Port the dev-beta2 progress-summary work onto the compositor-era dispatch:
- Post a one-line activity digest (🧠 N thoughts · 💬 N notes · 🛠️ N tool
calls · ⏱️ Ns, Discord parity) as a durable message when the progress
window collapses at end-of-turn, before the final answer. Counted
per-burst channel-side; only window-streamed activity feeds the bar
(durable rv/verbose items never do — persistent message XOR bar count),
no bar for error finals or turns where the window never rendered.
- Render multi-line commentary with its line structure intact (per-line
markdown conversion, joined as line breaks) instead of collapsing to
one run-on line; per-line conversion also keeps block markdown (setext
headings) from forming across lines.
