Confidence Score: 5/5

Safe to merge — the pre-processor only substitutes characters in place (output length is always equal to input length), and the bracket-depth guard logic is correct.

The underflow concern raised in earlier review rounds is fully addressed with explicit lower-bound guards before the slice operations. The bracket-depth stack correctly handles nested CSS-variable syntax and leaves all non-addClass/removeClass parentheses untouched. Tests exercise the original bug report, nested variable syntax, multi-class arguments, false-positive avoidance (addAttribute), and real-world component markup.

No files require special attention.

Walkthrough

This PR adds a Twig pre-processor module that rewrites addClass(...) and removeClass(...) calls by replacing opening and closing parentheses with spaces. The new Twig struct implements the PreProcessor trait with a process method that iterates through input bytes, detects these function patterns, maintains a parenthesis stack to track nesting, and normalizes delimiters. The pre-processor is declared and exported through the module system, integrated into the scanner to recognize .twig file extensions, and covered by unit tests and integration tests. A changelog entry documents the feature.
