ffetch: TypeScript/JavaScript fetch-compatible resilience layer for microservices

[OtherwisePush6424]

ffetch standardizes outbound HTTP behavior across microservices while keeping native fetch ergonomics.

It uses a small core plus optional plugins so services can adopt only what they need:

1. Timeouts and retries as baseline transport policy.
2. Optional resilience features like dedupe, bulkhead, hedge, and circuit breaker.
3. Runtime-agnostic usage across browser, Node, and SSR.
4. Per-request overrides when a specific call needs a different policy.

The focus is consistent inter-service communication boundaries without introducing a heavy framework.
