MITM proxy that intercepts HTTP 402 responses and auto-signs x402 payments via CWP (CLI Wallet Protocol). Uses companion-wallet or any CWP-compatible provider for signing — no private keys needed. Key components: - cwp-signer.ts: bridges @x402/evm ClientEvmSigner to CWP walletExec - proxy.ts: http-mitm-proxy that intercepts 402s and retries with payment - x402-client.ts: x402 protocol client (CWP-only, no private key path) - test-server.mjs: mock x402 server for testing Adds samples/* to workspaces and eslint config.
