bug: ERR_UNSUPPORTED_ESM_URL_SCHEME on Windows when loading --env config

[NathanMolTechno]

Description

Describe the bug

On Windows, running web-codegen-scorer eval --env=config.mjs fails with Error [ERR_UNSUPPORTED_ESM_URL_SCHEME]. This happens because the CLI passes an absolute Windows path (e.g., C:\path\to\config.mjs) directly to a dynamic import(). Node.js ESM loader interprets the C: as an unsupported protocol.

Steps to Reproduce

1. Use a Windows machine.
2. Install web-codegen-scorer globally or locally.
3. Run: web-codegen-scorer eval --env=angular-example
4. See error: Only URLs with a scheme in: file, data, and node are supported by the default ESM loader.

Error Stack with DEBUG enabled

$ export DEBUG=1&& web-codegen-scorer eval --env=angular-example
An error occurred during the assessment process:
Error [ERR_UNSUPPORTED_ESM_URL_SCHEME]: Only URLs with a scheme in: file, data, and node are supported by the default ESM loader. On Windows, absolute paths must be valid file:// URLs. Received protocol 'c:'

Environment

• OS: Windows 11
• Node version: v22.21.1 (and other ESM-enabled versions). Also tried Node 24
• Tool version: 0.0.69

Workaround for now is using Docker with Node base image. However it results in other issues while resolving, like not being able to install dependencies.
