feat(mpp-vscode): integrate ConfigManager for ~/.autodev/config.yaml

Phase 8 - Configuration Management Integration

Changes:
- Add ConfigManager service to load config from ~/.autodev/config.yaml
- Refactor ChatViewProvider to use ConfigManager instead of VSCode settings
- Mirror IdeaAgentViewModel's loadConfiguration() pattern
- Add lazy initialization of CodingAgent with proper config validation
- Create renderer that forwards events to webview (like TuiRenderer)
- Add 'Open Config' button in header and config prompt
- Support all LLM providers: openai, anthropic, deepseek, ollama, etc.
- Auto-create config template when file doesn't exist

Architecture:
- ConfigManager.load() → AutoDevConfigWrapper → getActiveConfig()
- isValid() check before agent initialization
- JsKoogLLMService + JsCodingAgent from mpp-core
- Renderer implements all JsCodingAgentRenderer methods

All 63 tests passing.
