Pull request overview

This PR updates the interactive “response mode” selection in the Launch CLI adapters to use a discrete selection prompt (instead of free-form text input), aligning the prompt UX with the existing buffered|streaming flag options.

Changes:

• Replaced the Response Mode prompt from input + validation to a list prompt with explicit Buffered / Streaming choices in both GitHub and FileUpload adapters.
• Simplified response mode handling logic by removing manual normalization/validation for s/b shortcuts.
• Updated Jest tests to assert the new prompt shape (type: 'list', choices) and adjusted parametrized cases accordingly.
