refactor(agent): reorganize emulator command handling for gRPC support

- Removed direct inclusion of `emulator_commands.h` in non-gRPC contexts to streamline dependencies.
- Updated CMake configuration to conditionally include emulator command sources only when gRPC is enabled, enhancing modularity.
- Ensured consistent handling of emulator commands across different components.

Benefits:
- Improved code organization and maintainability by clarifying the inclusion of gRPC-related features.
- Enhanced flexibility in managing command handlers based on compilation flags.
