[Feature Request] Code index does not index new folder in workspace

🧩 Description

Currently, when a new folder is added to the workspace, roo does not automatically index the code inside it. This results in missing files and symbols in search results, code navigation (e.g., "Go to Definition"), and other code intelligence features until a manual refresh or restart is triggered.

💡 Expected Behavior

When a new folder is added to the workspace:

• roo should detect this change automatically.
• It should trigger an incremental re-indexing process that includes the new folder and its contents.
• The newly indexed code should be available immediately (or within a short delay) for search and navigation.

🧪 Steps to Reproduce

1. Open a workspace in roo.
2. Create or add a new folder (e.g., utils/) containing source files (e.g., .rb, .ts, etc.).
3. Search code in new folder.
4. Observe that the folder is not indexed unless a manual action is taken.

🧰 Environment

• Roo version: 3.23.12
• OS: macOS
• Language(s): Ruby, JavaScript, etc.
• Workspace Type: Multi-folder workspace

🔄 Workaround

• Clear index and index again.

✅ Acceptance Criteria

• Automatically detect new folders/files added to workspace.
• Trigger partial/incremental indexing without user intervention.
• Indexed results should be available to all features relying on code search or navigation.
