Add String and StringView lexical_compare methods

- Implement lexical_compare for both String and StringView types
- Performs character-by-character comparison (UTF-16 code units) similar to Java's String.compareTo()
- Unlike Compare trait (which uses shortlex order), this compares purely on character values
- Add comprehensive documentation explaining the difference from Compare trait
- Add extensive test coverage including:
  - Equal/less than/greater than comparisons
  - Different length strings with same prefix
  - Case sensitivity and special characters
  - Emoji and surrogate pairs (UTF-16 behavior)
  - Empty strings and whitespace
  - Mixed ASCII and Unicode
- All 202 tests pass in the string package
