fix: resolve Unicode handling issues in comment processing

- fix byte-based string indexing breaking multi-byte Unicode characters
- convert all string operations to use []rune for proper Unicode support
- fix isPascalCase function to handle Unicode correctly
- properly track byte positions while counting runes in processCommentPart
- add comprehensive Unicode test cases including Cyrillic, Arabic, emoji
- handle invalid UTF-8 sequences gracefully

The core issue was using byte indexing (string[0]) instead of rune
conversion, which corrupted multi-byte characters like "Мария" to "ð�ария".
All string manipulation now properly handles Unicode characters.
