Flat 2分/1k input overcharged the DeepSeek relay ~20x (verified on 100:
H5-charged / goose accumulated_cost stayed at ~20x across every session).
The flat rate is decoupled from real provider cost, so it overcharges
cheap providers and would underbill expensive ones.
Extend the H5_USE_BACKEND_COST path with H5_MARGIN_MULTIPLIER: charge
upstream accumulated_cost(USD) × rate × margin, which tracks the provider
automatically. Falls back to the token path when the upstream omits
accumulatedCost, so the change is safe to ship dormant.
See docs/h5-metering-gateway.md for the metering-gateway design.
