fix(controller): disable daily session auto-reset for desktop (#542)

* fix(controller): disable daily session auto-reset for desktop

OpenClaw defaults to resetting all sessions daily at 4 AM, which
silently archives conversation history and starts a fresh session.
This is unexpected for a desktop chat app where users expect
persistent conversations. Switch to idle-based reset with a 1-year
timeout so sessions effectively never auto-reset, relying on
compaction (safeguard mode) to manage context window instead.

* fix(controller): tune compaction config for desktop assistant

Add recentTurnsPreserve: 5 (keep last 5 turns verbatim instead of
default 3) and enable qualityGuard (audit summaries for completeness
after compaction). Both improve context continuity for long-running
desktop sessions that no longer auto-reset daily.
