Problem (one or two sentences)

If the CodeIndexManager cannot connect to the embedder service, the extension gets stuck loading and never fully activates until all folders in the VSCode workspace fail.

Context (who is affected and when)

Any user who installs the Roo Code VS Code extension and opens a workspace without a running embedder service is affected. It happens during extension startup, regardless of OS or provider.

Reproduction steps

1. Install Roo Code VS Code extension (v3.28.18)
2. Break connection with embedder service
3. Open VS Code with a workspace that has multiple folders (any OS)
4. Observe extension output log
5. Extension remains stuck loading and does not finish activating until all folders fail; UI is unresponsive

Expected result

The extension should activate and show UI even if the embedder service is missing or misconfigured, showing a clear error and allowing the user to change config.

Actual result

Extension remains stuck loading. Output log reports: "[CodeIndexManager] Error during background CodeIndexManager configuration/indexing for /My/Path/To/Workspace: Failed to connect to the embedder service. Please check your connection settings and ensure the service is running." UI does not finish loading or allow interaction.
