The module docstring promised self-heal fix tasks 'wait for the CEO's
Approve-&-Start', but _originate created them confirmed_by_human=True and the
orchestrator dispatched them at once — a self-heal fix that re-broke CI would
trigger another cycle, open another auto-dispatched fix, and loop with no CEO
gate on dispatch.
Restore the documented gate:
* _originate opens the task confirmed_by_human=False (held for the CEO).
* The orchestrator holds a self-heal task out of both the PM and dev dispatch
paths until confirmed_by_human flips True.
* approve_and_start (the CEO's start gate) sets confirmed_by_human=True so the
held task finally dispatches (idempotent for board/intake tasks already True).
* list_pending_for_agent scopes the give_me_work hold to self-heal
(source != self_heal OR confirmed_by_human) so an already-alive PM can't grab
it pre-approval — while ordinary delegated subtasks (confirmed_by_human=False
by default, where the delegation IS the authorization) still dispatch.
The 'never self-deploys' guarantee (no merge) is unchanged.
