feat: add `get_info` method and protected access to key student info

- Added `get_info` method to return a concise summary of the student, including surname with initials, Git link, and primary contact method.
- Implemented individual methods for retrieving surname with initials, Git link, and contact information separately.
- Protected contact fields from direct modification; fields can now only be updated via `set_contacts`.
- Enhanced string parsing with `from_string` constructor to initialize objects directly from formatted strings.
- Updated main file to test new methods and constructor functionality.
