PR #137 review-leftover: the list of hidden Working-row labels leaves out "Compacting…" #139

[review-leftover] #137

• PR feat(fork): hide Working and Thinking rows outside Normal display mode #137 body, details list: "The Working row goes with all its labels" names "Compacting for 3s" but not "Compacting…", which CompactingLabel in apps/web/src/components/chat/TimelineWorkGroupRows.tsx shows on the same row when it has no start time. That label is hidden too. Add "Compacting…" to the list, or drop "all".

Non-blocking wording note from a passed review round; no code change.
