Jonathan Hui 254043deec [nexus] add gRPC support and live demo (#12898 )

This commit introduces gRPC support to the Nexus simulator, enabling
remote control and monitoring of simulations. This infrastructure allows
external tools and visualizers to interact with the simulated network
in real-time.

Key changes:
- Defined `simulation.proto` providing the `NexusService` definition for
  simulation control and event streaming.
- Implemented `GrpcServer` in `nexus_grpc.cpp` which functions as a
  Nexus simulation observer, pushing events to connected clients.
- Added RPCs for dynamic node creation, position updates, node state
  control, and network orchestration (forming and joining).
- Implemented a real-time event stream that includes node state changes,
  link updates, and packet captures (with basic protocol decoding).
- Introduced `nexus_native.cpp` as an entry point for a persistent
  simulation server that can be controlled via gRPC.
- Updated `Core` and `Observer` interfaces to support a list of
  concurrent observers instead of a single instance.
- Enhanced the CMake build system to optionally find and link against
  gRPC and Protobuf, including automatic source generation.
- Updated CI (GitHub Actions) to include build and test steps for the
  new gRPC functionality.
- Added comprehensive unit tests in `test_grpc.cpp` to verify all
  exposed gRPC service methods.
