Add the day plan she can recite when asked (#128)

The plan answers "какие планы на сегодня?" by putting one day in order:
calendar events (with #126's ambient provenance carried through and hedged),
pending reminders, and one line per morning routine that still has items
outstanding. "что дальше?" trims what has already passed.

It lives in internal/morning, not in a parallel system, because it is the same
question the checklist asks at a different scale — the routine knows what is
missing from a window, the plan knows what the whole day holds, and both read
the same facts and the same idea of "today". BuildPlan is pure; tickLoop.dayPlan
is the impure half that reads the store.

It is not a nag. Nothing here fires, schedules or announces: the plan is built
only when asked, over IPC (day_plan) or on the existing /morning page.
Unprompted delivery stays with the morning nudge and the dispatcher's policy.

The query source sits before "calendar" in querySources because both match
"…на сегодня" and the plan's matcher is the more specific one; IsDayPlanQuery
matches whole words so "планёрка" (a meeting) is not read as a request for the
plan, and refuses any utterance naming another day, since the plan is built for
the clock's own day only.

Verified: make build and make test both exit 0; new tests cover plan ordering,
the checklist-only-what-is-left rule, other-day rejection, the RU rendering
against the persona checks, rest-of-day trimming, the source ordering, and the
matcher's refusals.
