feat(mdxe): implement minimal MDXE with dynamic route handler and CLI

[devin-ai-integration]

Minimal MDXE Implementation

This PR implements a minimal version of MDXE that loads MD/MDX files from the consuming app's current folder using Next.js App Router with a dynamic catch-all route.

Features

• Dynamic route handler (src/app/[[...path]]/page.tsx) for rendering MD/MDX files
• File resolution utilities (src/utils/file-utils.ts) for finding and loading markdown files
• CLI implementation (bin/mdx-cli.js) for serving, building, and starting the application
• Main package exports (src/index.ts)

Implementation Details

• Uses Next.js App Router with a dynamic catch-all route
• Loads MD/MDX files directly from the consuming app's current directory
• Provides a simple CLI for serving, building, and starting the application
• Minimal dependencies and simplified architecture

Testing

The implementation can be tested by:

1. Running node bin/mdx-cli.js dev to start the development server
2. Creating some MD/MDX files in the current directory
3. Accessing them through the browser at the corresponding routes
