Subject: [PATCH] feat: initial VS Code extension for OpenClaude

Introduce OpenClaude as a first-class VS Code extension with:

- Built-in Control Center sidebar for seamless workflow integration
- Terminal-first design with authentic monospace UI and ASCII styling
- Quick-launch buttons for OpenClaude terminal, repository access, and command palette
- Status display showing runtime and OpenAI shim configuration
- Dark theme optimized for focus and extended development sessions
- Proper extension manifest with activation events and contribution points
- Debug configuration for local development

This extension provides developers with direct access to OpenClaude
without leaving VS Code, enabling a tighter integration with the editor.
