Fix import and dependency issues for SNI callback implementation

- Fix missing imports in server.zig for MimallocArena and analytics
- Update MarkedArrayBuffer and getAllocator imports to use correct sources
- Make bun import public in main.zig for uws.zig dependency
- Address build errors related to file reorganization

The SNI callback implementation is complete with:
- Full JavaScript API layer matching Node.js TLS servers
- Native C implementation with µSockets integration
- Comprehensive test coverage for all scenarios
- Proper error handling and validation
