WIP: Partial conversion of filesystem and everything servers

Browse Source 
Attempted to convert remaining servers to McpServer API but encountered
compatibility issues:

filesystem server:
- Uses advanced low-level Server features (roots protocol, notifications)
- McpServer doesn't expose: setNotificationHandler, listRoots, oninitialized
- Requires significant restructuring or staying on low-level API

everything server:
- Partially converted to use server.server for advanced features
- Has extensive TypeScript type errors with resource/content types
- Needs additional work to resolve all type mismatches

Updated dependencies:
- Removed prepare scripts to avoid circular build dependencies
- Updated module resolution settings in tsconfig
