Addresses feedback to extract hardcoded JavaScript/TypeScript extension checks into a reusable constant.

**Changes:**
- Extracted `COMMON_JS_EXTENSIONS` constant at module level
- Refactored match statement to use `.as_deref()` with `.contains()` instead of long conditional chain
- Removed now-unfulfilled `clippy::too_many_lines` lint expectation

**Before:**
```rust
match ext {
  Some(ext)
    if ext == "js"
      || ext == "jsx"
      || ext == "mjs"
      // ... 5 more conditions
  {
    relative_path
  }
  Some(ext) if !ext.is_empty() => {
    format!("{relative_path}.{ext}")
  }
  _ => relative_path,
}
```

**After:**
```rust
const COMMON_JS_EXTENSIONS: &[&str] = &["js", "jsx", "mjs", "cjs", "ts", "tsx", "mts", "cts"];

match ext.as_deref() {
  Some(e) if COMMON_JS_EXTENSIONS.contains(&e) => relative_path,
  Some(e) if !e.is_empty() => format!("{relative_path}.{e}"),
  _ => relative_path,
}
```
