Code Similarity Detection (Multi-Language)

What to do

Detect which languages are present in the target path and run the appropriate similarity tool. Then analyze results and propose refactoring.

Step 1: Detect language and select tool

Check the target path for file extensions:

Extension	Tool
.ts, .tsx, .js, .jsx	similarity-ts
.py	similarity-py
.mbt	similarity-mbt
.rs	similarity-rs
.php
