Subject: [PATCH] feat(frontend): add prompt refine button to MessagesTab
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a "Refine Prompt" button to the chat interface that helps users improve their prompts with AI-powered suggestions using heuristic-based refinement.

Features:
- Button appears next to Settings in the chat controls
- Uses Sparkles icon to indicate AI enhancement
- Shows loading state during refinement (800ms simulated processing)
- Provides instant feedback by updating the textarea
- Disabled when prompt is too short (< 5 characters)
- Disabled during active agent runs or while sending messages

Implementation:
- Added handleRefinePrompt() function with three heuristics:
  - Short prompts (< 30 chars): Adds context and structure
  - Unclear prompts: Adds action verb prefix
  - Single-line prompts (> 50 chars): Adds structured output format
- Added Sparkles icon import from lucide-react
- Added refining state to track button loading status
- Follows existing button patterns with loading states
