Add active files to file context menu (RooCodeInc#4048)

* Add active files to file context menu

Add support to include active files (open tabs) within the WorkspaceTracker. This enables the tracker to send the webview with a file list that has active files listed at the top.

The changes include:

- Listening for tab group changes using `vscode.window.tabGroups.onDidChangeTabs` to trigger workspace updates.
- Introducing an `activeFiles` getter that retrieves the file paths of all currently open text editor tabs.
- Modifying the `workspaceDidUpdate` function to include both `activeFiles` and `filePaths` when posting the `workspaceUpdated` message to the webview.

* use set
