⚡ Bolt: [performance improvement] array_map and array_filter loop fusion

[TavoNiievez]

💡 What: Replaced chained array_map and array_filter calls with a single foreach loop when extracting string roles in src/Codeception/Module/Symfony.php. Removed corresponding unused imports.

🎯 Why: Fuses two array iteration loops into a single pass. Eliminates intermediate array allocations and the overhead of calling is_scalar and strval string callbacks via array_filter and array_map.

📊 Impact: Minor reduction in memory usage and execution time during security profile debugging by avoiding intermediate arrays and closure dispatch overhead.

🔬 Measurement: Verify with vendor/bin/phpunit tests/ and vendor/bin/phpstan analyse src --level=max to ensure type-safe scalar extraction remains functionally equivalent.
