Proposed changes

Change the startup process for feature extensions.

With the initial implementation for worker process startup (controlling the startup process with a semaphore) and the fix for #62 (starting the worker if it was stopped when accessed), there is no longer a need to pre-start all workers.

Simplify the logic for the extension startup process and remove unnecessary source code.

Additionally, add E2E tests related to changes in the ConfigFilePattern in Settings.
