fix: resolve vscode module import issue in webview build

- Separate vscode-dependent code into vscode-utils.ts
- Create wrapper module to conditionally use vscode functionality
- Update all imports to use the wrapper instead of direct imports
- Initialize vscode utilities during extension activation
- This prevents the webview build from failing due to vscode module not being available in browser context

+## Summary
+
+This PR fixes issue #6720 where Roo Code incorrectly identifies the .roo folder location in multi-root workspaces. When .roo is added as one of the workspace folders, it should be recognized directly rather than being treated as a subdirectory of another workspace folder.
+
+## Problem
+
+In multi-root workspaces, when .roo is added as a workspace folder, Roo Code was still creating/looking for .roo as a subdirectory of the first workspace folder instead of recognizing the existing .roo workspace folder.
+
+## Solution
+
+- Added `findWorkspaceWithRoo()` utility function to detect when .roo is one of the workspace folders
+- Updated `getProjectRooDirectoryForCwd()` to return the .roo workspace folder path directly when it exists
+- Updated all direct .roo path constructions throughout the codebase to use the centralized utility functions
+- Added comprehensive tests for multi-root workspace scenarios
+
+## Changes
+
+- **src/services/roo-config/index.ts**: Added `findWorkspaceWithRoo()` and updated `getProjectRooDirectoryForCwd()`
+- **src/core/webview/webviewMessageHandler.ts**: Updated to use `getProjectRooDirectoryForCwd()`
+- **src/services/mcp/McpHub.ts**: Updated to use `getProjectRooDirectoryForCwd()`
+- **src/services/marketplace/SimpleInstaller.ts**: Updated to use `getProjectRooDirectoryForCwd()`
+- **src/core/config/CustomModesManager.ts**: Updated to use `getProjectRooDirectoryForCwd()`
+- **src/services/roo-config/**tests**/index.spec.ts**: Added tests for the new functionality
+
+## Testing
+
+- Added unit tests for `findWorkspaceWithRoo()` function
+- Added tests for `getProjectRooDirectoryForCwd()` with multi-root workspace scenarios
+- All existing tests pass without regression
+- Manually tested in VS Code with multi-root workspaces
+
+Fixes #6720
