tmux.Server.SetCommandAlias

SetCommandAlias replaces the complete "command-alias" server option array with SparseArraystring, preserving holes and empty values (tmux 3.2a or later). Read it with ServerOptionValues.CommandAlias from Server.Options ; Server.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.
