ZeroDev Bundler & Paymaster RPC

JSON-RPC 2.0 over HTTPS. All calls are an HTTP POST of a {jsonrpc,id,method,params} envelope to a single project-scoped URL: https://rpc.zerodev.app/api/v3/{projectId}/chain/{chainId}. Authentication is by projectId embedded in the URL path. The same endpoint serves both bundler and paymaster methods; append ?provider=ULTRA_RELAY to route through UltraRelay.
