The foreign path stored nothing for a ladder not_saved decision, but logged
it as "No certain prompt" and, when only the legacy answer was a
switched-off node's text, kept the file waiting for a seal that could only
store nothing. Such a decision now ends the wait at settle, and both settle
and the re-check log the opted-out path's own line (a wired switch says so).
Tests cover an only-PromptManager node switched off (opted out, not
foreign), a switched-off PromptManagerText behind a pass-through into a
core CLIPTextEncode, a wired switch, a negative-only switched-off node,
recorded history holding the off text, and foreign saving off.
