refactor: Remove obsolete server.ts file

- Deleted unused server.ts (451 lines) - old implementation not referenced anywhere
- Removed server.ts exclusion from jest.config.js coverage
- All functionality is in index.ts (4979 lines) which is the main entry point
- Tests pass, build succeeds

This reduces confusion and potential maintenance issues from having two server implementations.
