mavend: let a fact close the nudge that asked for it

The snooze wire had one end. "готово" and "выпил воды" both left the nudge
pending, so the auto-tuner only ever learned from deferrals and from
silence — never from the rule working.

Two entry points, because the two utterances are different acts. A bare
"готово" carries no content and is intercepted before the router, sharing
pendingNudge and the twenty-minute window with the snooze. "выпил воды" IS
content: it routes normally, writes its fact, and only then closes the
nudge (ackFromFact, after applyAction). Folding the second into a pre-route
intercept would have thrown away the thing he actually said.

ackFromFact is silent. The fact reply stands; "отлично, отметила" on top
would be her congratulating him for obeying, which is the nag she is not.

Which fact answers which rule comes from the rule's own InertWhenNoData, so
a rule added later is covered the day it lands. "да" and "ок" stay out of
the ack vocabulary: the clarify gate upstream has the stronger claim on
them, and a stray "да" must not rewrite the feedback signal.
