Stop hook fallback antok 200K-vindu. På Opus 4.7 (faktisk 1M) kunne
auto-handoff fyre 5–7x for tidlig — estimert 70% når reell bruk var
~14%. Erstatter enkel fallback med 4-stegs resolution-kjede:
1. payload.context_window.used_percentage (autoritativ)
2. payload.context_window.context_window_size + transcript-estimat
3. MODEL_WINDOWS[payload.model.id] + estimat
4. FALLBACK_WINDOW=1_000_000 + estimat (2026-default)
additionalContext-meldinger inkluderer nå [kilde: <source>] for innsyn.
