const MAX_EXITED_STATUS: usize = 512;Expand description
Per-shell stop handles + status. ShellStop fires the oneshot; ShellInput
sends to the stdin relay; ShellStatus reads the live status arc.
Lives in AppState.shell_sessions.
Max number of EXITED shell statuses retained for post-exit ShellStatus
queries. Running shells are always kept regardless of this cap; only
exited entries beyond it are evicted oldest-first. Bounds memory for
long-lived sidecars that spawn many short shells.
