Add Storybook + Playwright visual regression testing for the VS Code
extension's composite webview UI. This tests the full composition of
kilo-ui components with extension-specific contexts and styles.
- .storybook/ config with kilo-vscode theme defaults
- StoryProviders mock wrapper for DataProvider, SessionContext, etc.
- 7 composite stories: tool+permission, permission dock, tool cards,
chat idle/busy, multi-tool assistant message
- Playwright config on port 6007 with auto-discovery
- CI workflow updated with parallel kilo-vscode visual regression job
- Exported SessionContext and LanguageContext for story use
