fix: switch to Bundler module resolution for proxy-agent compatibility

proxy-agent v7 uses the `exports` field in package.json, which requires
moduleResolution "Bundler" or "NodeNext". Since esbuild handles bundling
to CJS, "Bundler" + "ESNext" is the correct TypeScript configuration for
type-checking only. Also update test type casts for the new ProxyAgentOptions
union type.
