Harness spec 3.5.0: scheduled work on a linked computer

Accept scheduled work (remote.scheduled, off by default) said as limits.scheduled; a scheduled
turn is an agent session marked `scheduled` in the schedule's mode (Edit when none chosen, Plan
refused, lowered to remote.max_mode) with its Min/Max; the answer reports status ok, silent,
failed or cancelled and the final reply. Approvals wait the schedule's wait and go to the person
through the server, then count as denied. _lembas/monitor runs a watch command under the mode's
rules (one that would ask is refused) and answers a hash and an excerpt. Schedule routes of
/api/v2 accept the device's token. team_add under a sub-manager names it (added_under).
Conformance areas scheduled, silent, monitor; team cases changed.
