Add new WithoutOutput() option that disables visual output while preserving raw mode for proper keyboard input handling. This allows arrow keys and other special keys to work without requiring Enter, while standard output functions like println() and logging libraries work correctly. This solves a common issue where users want Bubbletea's input handling but need to use standard output for logging or debugging without the renderer interfering with cursor positioning. Changes: - Add WithoutOutput() option in options.go - Add disableOutput flag to Program struct - Use term.MakeRawOutput() when disableOutput is enabled - Add counter example demonstrating the usage - Update go.mod with local x/term replace directive for development The implementation uses the new term.MakeRawOutput() function which sets raw mode for input while preserving output processing flags (OPOST/ONLCR), ensuring that newlines are automatically converted to CR+LF as expected by standard output functions.
