feat(ecosystem): add CryptoAPIs facilitator

Non-custodial x402 facilitator settling USDC on Base and Solana, mainnet
and testnet.

Endpoints are live and publicly verifiable without a credential:
  GET https://ai.cryptoapis.io/x402/merchant/supported
  GET https://ai.cryptoapis.io/x402/merchant/discovery/resources

/supported advertises the served kinds, the implemented extensions
(payment-identifier) and the signer addresses keyed by CAIP-2 namespace
pattern; /verify and /settle require a merchant API key and answer with
the spec's standard error codes.

The declared networks mirror /supported exactly — the four with an enabled
USDC asset — rather than every family the implementation supports, so the
listing never promises a chain /verify would reject.
