refactor(index.ts): filter out test files from activity modules

- Updated the activity module import logic in index.ts to exclude test files (ending with .test.ts and .test.js) from being loaded. This change ensures that only relevant activity modules are included, improving the clarity and performance of the worker.

These modifications enhance the organization of the codebase by preventing unnecessary test files from being processed.
