fix(processor): add string-aware comment detection to prevent URL corruption

- Implement findCommentIndex function that respects string boundaries
- Preserve URLs and strings containing '//' (e.g., https://example.com)
- Handle escaped quotes and multiple quote types (single, double, backtick)
- Prevent data corruption in config files and code containing URLs
