✨ UI: Minimalist Claude-style Redesign for Desktop App

[iotserver24]

Minimalist UI Redesign for Desktop App

This PR updates the React desktop UI (packages/desktop) to feature a clean, flat, grayscale-focused aesthetic similar to Codex Desktop, Claude Desktop, and Cursor, as requested by the user.

🎯 What changed

• MessageBubble.tsx: Removed right-aligned chat bubble layouts in favor of full-width, left-aligned message blocks with square text avatars (U for User, X for Assistant).
• ToolCallCard.tsx: Replaced the heavy, bordered card look with a clean, border-left threaded log style. Removed bg-* and border-* accents to utilize a neutral, monochrome color palette (while keeping core text colors readable).
• ChatPanel.tsx: Reduced the input floating pill shape from rounded-3xl with a heavy background to a flatter rounded-lg with a transparent background.
• Code Blocks: Removed backgrounds and borders from <pre> blocks within both Markdown text and tool execution logs to make the interface more seamless.

💡 Why

The user requested a better, cleaner UI for the desktop app similar to "Claude code desktop app" / "Codex". The previous UI used heavy iMessage-style right-aligned bubbles and distinctly boxed elements which added visual noise.

✅ Verification

• A local visual verification was performed using a headless Playwright script against the live pnpm dev environment to confirm all layout and styling adjustments render accurately.
• Ran pnpm run test and pnpm run lint from the monorepo root successfully.
