Merge: a reminder said whole is not asked about (#214)

V-572. "напомни в 11:00 позвонить маме" answered "Когда?". ReminderGrammar
builds its slots by hand and the extractor never ran over a stage 0 decision,
so HasTime was false however clearly the hour was spoken, and missingFor read
the silence as absence.

fillMatchedSlots in internal/router/router.go now runs the stage 2 extractor
over every stage 0 decision and fills only what the grammar left empty. A
matched value always wins. The LLM path had the same hole and the same fix, so
both share one function rather than ten grammars re-implementing extraction.

Slots.Text is deliberately not filled. A grammar that left Text empty meant
it: agendaQueryBuild hands the query chain the sentence itself. Filling it
would also make SlotText unaskable, which is the bug V-383 fixed on the LLM
side.

Enabled for all ten grammars and inert for nine. Extract fills Time for a
reminder, Fn for an act and Key for a fact, and nothing for query, system,
note or chat. Benchmarked at 20000x with the real date parser: every stage 0
shape stays inside the noise, and the reminder rule gains, because
actionReminder was already running that same parse one layer down.

TestONNXBaseline 64/91 before and after, no case regressed. The fixture's own
"slots deferred to daemon" line went 6 to 0. On the box: "хорошо, напомню
сегодня в 11:00."

Conflict in internal/router/router.go resolved by hand: V-564's grammar-outcome
note and V-572's slot fill both belong, fill first. Full -race suite green.

--no-verify: the pre-commit hook refuses master, and the owner asked for
straight-to-master merges for this unattended run.
