Before: The feed gave no sense of how far an agent had got. Agents could
not post a progress report that the feed understands: `comment add` had no
way to set a comment type, and the run brief told agents not to post
progress at all.
After: Each feed message shows a compact checklist under its thread bar
(done/total, a small bar, the first 5 items, "+N more"), and the issue peek
shows the same block under its title. Finished issues (done or closed
category) fold to a single "done/total" line with a chevron to expand. A
progress report is a `progress_update` comment by an agent whose body is a
Markdown task list; the newest one per issue wins.
How: The thread-summaries endpoint gains `latest_progress`
({comment_id, content, created_at} | null) from one batched DISTINCT ON
query, so there is no new endpoint. Core adds the type, a tolerant zod
schema, `parseProgressChecklist`, and a realtime patch for new reports.
Views add `FeedProgressCard`, mounted from the thread bar and the peek, with
strings in all five locales. `multica issue comment add --type
progress_update` lets agents post a report, and the run brief documents it as
the one exception to the single-comment rule.
