Option to disable suggested prompts / autocomplete in input field

Feature Request

When the Claude Code input field is empty, suggested prompts appear that can be selected. Pressing Enter on an empty field submits whatever suggestion is highlighted.

Problem: This causes accidental submissions, especially when using voice input (e.g., Wispr Flow) with auto-submit functionality. The auto-submit detects typing has stopped and presses Enter, but if the field appears empty with a suggestion highlighted, it submits the suggestion instead of the intended prompt.

Requested feature: Add a setting to disable these suggested prompts/autocomplete, such as:

• suggestedPrompts: false in settings
• A CLI flag like --no-suggestions

Use case: Voice-controlled workflows where auto-submit is triggered after transcription completes. Having suggestions enabled interferes with this flow.

Thanks!
