T36: programs report their status through OSC 7501, revision 0.4, checked as the spec checks them; each terminal keeps their records by id, replaced whole, cleared with those under them, 256 at most; a new prompt drops working, blocked and idle, a full reset all; the support query is answered with every state and kind, ahead of a DA1 sent after it; the pty's tests move to their own file
