Terminal construction previously accepted GhosttyTerminalOptions with dimensions and one scrollback byte limit. Remove the options struct from the ABI and make ghostty_terminal_new accept columns and rows directly. Add byte and line limit options to ghostty_terminal_set and forward them to the runtime Terminal setters. NULL removes a limit, while zero bytes disables scrollback. Update type metadata, tests, and all API examples.
