@reckon402/facilitator-client

Two HTTP clients implementing the Facilitator interface from @reckon402/types:

• CdpFacilitator — wraps https://x402.org/facilitator (the x402 Foundation open testnet facilitator). Preserved from L2 for fallback and comparison.
• Reckon402Facilitator — wraps https://facilitator.reckon402.com/x402 (our own facilitator worker, L3+). Canonical x402-v2 fields at the top of responses; Reckon402 X35 extensions (paymentId, requestId, state, receipt) carried through as extra fields.

Both expose the same shape:

interface Facilitator {
  verify(payload, requirements): Promise<FacilitatorVerifyResponse>
  settle(payload, requirements): Promise<FacilitatorSettleResponse>
}

Swapping between them is a one-line constructor change at the middleware call site.
