Greptile Summary

This PR fixes a Vite SSR warning on macOS by replacing a manually constructed file:// URL template literal with the proper pathToFileURL utility from Node's built-in node:url module when dynamically importing the project's prettier config file.

• Adds import { pathToFileURL } from 'node:url' to packages/cli-helpers/src/lib/index.ts
• Replaces `file://${prettierConfigPath}` with pathToFileURL(prettierConfigPath).href in getPrettierOptions
• pathToFileURL is the idiomatic, correct way to convert a file-system path to a file: URL — it handles special characters, platform differences (Windows drive letters), and produces a properly encoded URL that satisfies Node.js and Vite's URL host validation on darwin

Confidence Score: 5/5

• This PR is safe to merge — it's a targeted, idiomatic one-liner fix with no risk of regression.
• The change is minimal (one import + one expression replacement), uses the standard Node.js utility for the job, is cross-platform correct, and directly addresses the reported Vite warning. No logic is altered beyond URL construction.
• No files require special attention.
