/**
 * Language Detection example - standalone version
 *
 * Demonstrates language detection from filenames.
 * This is a pure function that maps file extensions to language identifiers.
 *
 * To run:
 *   node language_detection.js
 *
 * Expected output:
 *   Testing language detection from filenames...
 *   script.py -> python
 *   app.js -> javascript
 *   main.go -> go
 *   Cargo.rs -> rust
 *   Main.java -> java
 *   test.rb -> ruby
 *   index.ts -> typescript
 *   unknown -> null
 *   Language detection complete!
