Fix keyboard shortcuts for non-QWERTY layouts

Replace deprecated event.keyCode with event.key to support Dvorak, AZERTY, and other keyboard layouts. This ensures the Enter key shortcut works consistently regardless of the user's keyboard configuration.

Users were able to send messages containing only whitespace characters,
which created empty-looking messages in the chat. This fix trims the
input before validation, preventing whitespace-only messages from being
submitted.

Changes:
- Updated MessageInput submit function to use .trim() before checking
  if message is empty (App.tsx:426)

Fixes: #2
Fix whitespace-only message submission bug
Added a copy button that appears when hovering over code blocks in chat messages.
This improves developer experience by allowing one-click copying of code snippets.

Features:
- Copy button appears on hover over code blocks
- One-click copying to clipboard
- Visual feedback shows "Copied!" with green background for 2 seconds
- Smooth fade-in/fade-out transitions

Changes:
- Modified markdown-it highlight function to wrap code blocks with copy button (Block.tsx:42-52)
- Added useEffect hook to handle clipboard copy functionality (Block.tsx:89-123)
- Added CSS styling for copy button with hover effects (App.css:5-52)
- Added contentRef to Box component for DOM manipulation (Block.tsx:201)
Add copy button to code blocks
Implemented drag-and-drop to allow users to reorder chat sessions in the sidebar.
This enables better organization by allowing users to arrange sessions by priority
or topic rather than chronological order.

Features:
- Drag sessions to reorder them in sidebar
- Visual feedback during dragging (opacity and cursor changes)
- Blue border indicator shows drop position
- Order persists across sessions via store
- Smooth animations for reordering

Changes:
- Added reorderSessions function to store for managing session order (store.ts:154-159)
- Updated SessionItem with drag-and-drop event handlers (SessionItem.tsx:46-76)
- Added draggable attributes and visual state management (SessionItem.tsx:83-98)
- Passed index and reorderSession props from App.tsx (App.tsx:199, 211)
- Added CSS styling for drag states (App.css:54-63)

Technical Implementation:
- Uses HTML5 Drag and Drop API
- State management for isDragging and isDragOver
- Data transfer via dataTransfer API with index tracking
- Automatic session persistence through existing store mechanism
