fix: detect newly added folders in workspace dynamically

- Added workspace folder change listener in extension.ts
- Convert codeIndexManagers from array to Map for better tracking
- Implement logic to create CodeIndexManager for added folders
- Implement logic to dispose CodeIndexManager for removed folders
- Add handleWorkspaceFoldersChanged method to ClineProvider
- Fixes #8886
