fix: correct operator precedence in ZynML syntax highlighting

- Separate equality (==, !=) from assignment (=) patterns
- Move equality comparison before assignment to ensure == matches first
- Separate fat arrow (=>) from thin arrow (->)
- Make type annotation colon (:) punctuation instead of operator
- Move path separator (::) before single colon
- Add compound assignment patterns (+=, -=, etc.)
- Move bitwise shift (<<, >>) before comparison operators
