createJavaScriptExtractor

function createJavaScriptExtractor(): Extractor;

Create a JavaScript/TypeScript extractor.

This extractor:

• Receives pre-filtered candidates (files and directories)
• For directories with package.json: treats as multi-file package example
• For files with frontmatter: treats as single-file example
• Extracts metadata from package.json or frontmatter
• Loads raw content into ExampleFile
• Respects exclude patterns (default: node_modules, .git, dist, build)
• Tracks claimed files for conflict detection
