AGENTS.md: record that companion-app has drifted 6 days behind the panel

Found while auditing what's needed for a real iPhone build: src/screens/
hasn't changed since 2026-08-11, so none of the panel work since then
(HIG audit rounds, receipt upload, trip editing, Inspektion forecast,
Heckklappenschloss removal, ...) exists in the phone app yet.

+- [ ] **New gap found while auditing "what's needed for a real iPhone app" (2026-08-17):**
+      `companion-app/src/screens/` has not been touched since 2026-08-11 (`git log -1` on that
+      path) — every panel fix and feature from the six days of sessions since (the full HIG audit
+      rounds, receipt drag/paste upload, trip editing, Ankunftszeit, Inspektion forecast,
+      Heckklappenschloss removal, the Tag-theme placeholder fix, all of it) exists **only** in
+      `homeassistant/www/audi-dashboard-app.js`, not in the companion app. The two codebases are
+      independent implementations of the same product, not a shared component — nothing in this
+      repo currently keeps them in sync automatically. Whoever next works on the companion app
+      needs to either treat this as a deliberate "port everything since 2026-08-11" task, or
+      explicitly decide the divergence is acceptable for now. Not scoped or started.
