Add vsock-based communication to manager

Browse Source 
Introduced virtual socket (vsock) communication abilities in the manager package by implementing a new socket service. This includes establishing a vsock listener and stub methods for sending computation results and cleaning up resources. The addition provides the groundwork for interprocess communication between guest and host in virtualized environments.

- Integrated the `mdlayher/vsock` library for handling virtual socket operations.
- Created a new `sockService` struct to encapsulate vsock listener handling.
- Implemented `NewVsock` constructor to initialize the listener with domain value `3`.
- Added placeholder methods for future computation sending and service closing logic.

This enhancement targets scenarios where efficient VM-to-host communication is required.
