query_project: implement the standup view (#28)

The StandupScreen already renders drift + plan + nag from real data (standup-view,
#52), but the agent's query_project standup view was a `notImplemented` stub, so
Reginald couldn't answer standup questions from deterministic data.

Implement `standupView(snap, asOf)`: today's plan (the scheduler's earliest pick
per person, with why — critical path / blocks / order), overnight drift (real
anomalies: issues sitting in review, or steeping past their estimate), and the
single stalest blocker to nag about (+ what it blocks). All deterministic; the
model narrates. Added 'standup' to the query_project tool's view enum.

Acceptance met: standup surfaces schedule drift + at least one stale blocker
(and stays calm — no nag, empty drift — when nothing is steeping). +2 core tests;
typecheck clean.
