When /rewind is invoked via the picker, the callback (_do_rewind) truncates session messages and calls _remount_current_session(), which removes all widgets from the container. Back in _collapse_choice(), the anchor widget reference still exists but is now detached, causing a crash on mount(after=anchor). Add a guard that checks is_mounted on the anchor widget after the on_select callback. If the callback already rebuilt the UI, return early to avoid operating on detached widgets. Closes lsdefine#421

When
/rewindis invoked via the picker in the TUI, the callback(
_do_rewind) truncates session messages and calls_remount_current_session(), which removes all widgets from the#messagescontainer. Back in_collapse_choice(), the anchor widgetreference (
msg._hint_widget/msg._body_widget) still exists but isnow detached, causing a crash when trying to
container.mount(after=anchor).Fix: Add a guard after the
on_selectcallback that checksanchor.is_mounted. If the callback already rebuilt the UI (anchor isdetached), return early to avoid operating on detached widgets.
For normal callbacks that don't remount, the anchor widgets remain
mounted and the guard is a no-op — behavior is unchanged.
Closes #421
