During a compaction pass, bare `status` ticks from claude are the only
live signal (no dedicated progress event exists in the headless stream-json).
Previously these rendered as a coalescing `⚙ status` row — uninformative
while waiting for a long compact to finish.
The harness emits `TurnStateChanged { state: Compacting, since_unix }`
immediately before invoking `session.compact()` for both the turn-end and
idle-session manual-compact paths. The frontend already tracks this in
`stateName` / `stateSince` for the state badge (`📦 compacting · Xs`);
now the terminal's `status` tick renderer reads the same two variables so
consecutive ticks show `⚙ compact · Xs…` (elapsed, in-place updating via
the existing coalescer) instead of the unhelpful `⚙ status`.
Result: what used to look like
⚙ status
⚙ compact · manual · 37k→2k tokens · 40.1s
now looks like
⚙ compact · 3s… (updating in place)
⚙ compact · manual · 37k→2k tokens · 40.1s
Auto-compact (triggered by hive-claude's InfiniteSession policy internally,
no TurnState::Compacting set by the harness) continues to show `⚙ status`
as before.
Addresses #2276 (follow-up to status-tick coalescing in #2335).
