misc(refactor): extract command handlers and centralize error handling

Browse Source 
- Move command-specific logic out of main.rs into Server::handle_* methods
  (parsing remains in main and handlers accept already-parsed input).
- Handlers now return Result and return Err("ERROR:...") instead of sending
  error messages directly to clients.
- main.rs now logs handler errors to console and sends the error string to
  the client (removed `continue` statements after error sends).
- Move end_game_check from main.rs into lib.rs for reuse.
- Update handler implementations to follow the new error-returning pattern.
