feat: Implement CLI session-based Full Stack mode

Replaces WebContainer-based approach with simpler Claude Code CLI session shell command execution. This eliminates COOP/COEP header requirements and reduces bundle size by ~350KB. Changes: - Added executeShellCommand() to ClaudeService for spawning bash processes - Added /claude/api/shell-command API endpoint for executing commands - Updated Full Stack mode (chat-functions.js) to use CLI sessions - Simplified terminal mode by removing WebContainer dependencies Benefits: - No SharedArrayBuffer/COOP/COEP issues - Uses existing Claude Code infrastructure - Faster startup, more reliable execution - Better error handling and output capture Fixes: - Terminal creation failure in Full Stack mode - WebContainer SharedArrayBuffer serialization errors Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
