muxr v3.6.2 Reclaim interrupted-but-quiet turns by default. An interrupted Claude turn fires no Stop hook, so its busy state file is never cleared to idle; the default File probe trusted it until stale_busy_secs (1h), so upgrade skipped the session and recycle waited out its timeout. The default probe now corroborates a still-busy verdict against tmux pane activity: pane quiet for >= max(min_idle, 120s) means the turn was interrupted and the session is reclaimed now. Conservative -- a live turn keeps the pane refreshing, the 120s floor protects recycle's 5s window, and stale_busy_secs remains the backstop when tmux activity is unavailable. Promotes ADR 0003's opt-in reclaim into the core default. ADR 0007.
