+ * Declaratively set the tab-status indicator (OSC 21337).
+ *
+ * Emits a colored dot + short status text to the tab sidebar. Terminals
+ * that don't support OSC 21337 discard the sequence silently, so this is
+ * safe to call unconditionally. Wrapped for tmux/screen passthrough.
+ *
+ * Pass `null` to opt out. If a status was previously set, transitioning to
+ * `null` emits CLEAR_TAB_STATUS so toggling off mid-session doesn't leave
+ * a stale dot. Process-exit cleanup is handled by ink.tsx's unmount path.
