    Interface RateLimitStore

    Fixed-window rate-limit counters keyed by connector id. Implementations back the manifest's rateLimit budget. The store's reach IS the budget's reach: InMemoryRateLimitStore caps per isolate (per RUN under DO-per-run routing); a declared cap that must hold across isolates needs D1RateLimitStore (or an equivalent shared store).

    interface RateLimitStore {
        increment(
            key: string,
            windowMs: number,
            now: number,
        ): number | Promise<number>;
    }
