merge templates, shortcuts, prompts into ai settings

[ComputelessComputer]

Overview

Consolidate all AI-related configuration into a unified AI Settings view. This merges templates, shortcuts, and prompts into a single cohesive settings area.

Scope

This issue consolidates:

• templates view #2543: templates view (to be closed)
• shortcuts view #2545: shortcuts view (to be closed)
• Prompts configuration

Design

AI Settings Sections

1. Templates

   • Create, edit, delete templates
   • Template categories/organization
   • Default template selection
   • Template preview

2. Shortcuts

   • Keyboard shortcuts for AI actions
   • Custom shortcut mapping
   • Shortcut conflict detection

3. Prompts

   • Custom prompt management
   • System prompt configuration
   • Prompt templates for different use cases
   • Prompt variables/placeholders

4. General AI Settings

   • Model selection (local vs cloud)
   • API key configuration
   • Generation parameters (temperature, max tokens, etc.)

Rationale

All these features are related to AI configuration and belong together for a cohesive user experience. Having them in separate views creates unnecessary navigation overhead.

Acceptance Criteria

• Unified AI Settings view with tabbed or sectioned layout
• Templates management integrated
• Shortcuts management integrated
• Prompts management integrated
• Existing AI settings (model selection, etc.) preserved
• Smooth migration from any existing separate views
