Feature request: setting to disable/hide the auto-generated prompt-suggestion list

Problem
The desktop app shows an auto-generated list of suggested prompts (built from past session titles / prompt history) in the new-session input area, e.g. under a "Morning session suggestions" header with a "Show N more" expander. There is currently no way to turn this off. It repeats items, surfaces old one-off prompts ("Delete all content", "Transfer files to external drive"), and clutters the input for users who don't want it.

Request
Add a setting to disable or hide the prompt-suggestion / recommended-prompts feed. Ideally:

• a settings.json key (e.g. "showPromptSuggestions": false), and/or
• a UI toggle in Settings.

Why
No documented settings.json key, env var, /config toggle, or UI control exists to hide it today (confirmed against the Desktop and Settings docs). The only current workaround is deleting local session history, which is destructive and unrelated to the goal.
