tmux.Session.SetStatusFormat

SetStatusFormat replaces the complete "status-format" session option array with SparseArraystring, preserving holes and empty values (tmux 3.2a or later). Read it with SessionOptionValues.StatusFormat from Session.Options ; Session.UnsetOption restores inheritance or the global default. Replacement is not atomic: the result reports confirmed writes, and failures stop without rollback. Serialize concurrent replacement of the same target and option.
