Brooklyn Nicholson 715b691723 fix(desktop): show summarizing indicator during auto-compaction
Auto-compression rewrites history mid-turn, which made long threads look
like they reset. Re-tag the gateway lifecycle status as compacting and
surface it in the desktop thread loading indicators.

"""Auto-compaction status re-tagging for the desktop "Summarizing…" indicator.
Auto-compaction reaches the gateway as a generic ``lifecycle`` status. The
gateway re-tags it as ``kind="compacting"`` so drivers (the desktop app) can
show an explicit summarizing indicator instead of the transcript appearing to
silently reset mid-turn.
