perf: API budget pacing — stretch usage from 3h to 5h

- God interval: 2min → 5min (biggest consumer, ~60% of budget)
- God timeout: 10min → 5min
- God skips when nothing changed (no new turns/pushes/stage changes)
- CC Worker timeout: 5min → 3min (faster iteration, less token per task)
- Turn interval: 15s → 25s (reduce A2A fallback frequency)

Estimated savings: ~40% reduction, extending 3h budget to ~5h.
