refactor(compiler): rename variable for clarity

- Changed $candidate to $autoloadFile for better readability
- Updated variable references in conditional check
- Maintained same logic for autoload file path construction
- Kept existing rtrim functionality for directory separators
- Preserved array uniqueness check with in_array function
