feat: add client-side builtin module check in module runner

[jiji-hoon96]

Description

Fixes #20840

This PR moves the isBuiltin check from the server side to the module runner side to avoid unnecessary server round-trips when importing builtin modules (e.g., node:fs, node:path).

Module runner checks builtin modules client-side first. The server-side check remains as a fallback for custom runner implementations.

Changes

• Added createIsBuiltin utility in module-runner/utils.ts
• Added builtins option to ModuleRunnerOptions interface
• Module runner performs client-side builtin check before calling server
• createServerModuleRunner automatically passes builtins config to runner
