mctp-api: add Stack facade and update mctp_echo to use high-level traits

- Add services/mctp/api/src/stack.rs: Stack<C: MctpClient> facade that
  wraps any MctpClient and returns StackListener, StackReqChannel and
  StackRespChannel implementing the MctpListener / MctpReqChannel /
  MctpRespChannel traits. All channel types release server handles on Drop.

- Update services/mctp/api/src/lib.rs: expose stack module and re-export
  Stack, StackListener, StackReqChannel, StackRespChannel.

- Update target/ast1060-evb/mctp/mctp_echo.rs: replace direct MctpClient
  calls with Stack::new(IpcMctpClient) + MctpListener / MctpRespChannel
  traits, matching the Hubris mctp-echo task structure.

- Update services/mctp/server/tests/integration.rs: add Stack facade tests
  exercising echo-via-Stack and req/resp roundtrip using DirectClient as
  the MctpClient strategy.

- Update services/mctp/api/README.md: document the two-layer abstraction,
  Stack API, Strategy pattern, and wire protocol.

Getting Started

This project uses cargo-xtask for build automation and project management.

Available Tasks

You can run tasks using cargo xtask <task-name>:

  • cargo xtask build - Build the project
  • cargo xtask test - Run all tests
  • cargo xtask check - Run cargo check
  • cargo xtask clippy - Run clippy lints
  • cargo xtask fmt - Format code with rustfmt
  • cargo xtask clean - Clean build artifacts
  • cargo xtask dist - Build a distribution (release build)
  • cargo xtask docs - Build documentation with mdbook
  • cargo xtask cargo-lock - Manage Cargo.lock file
  • cargo xtask precheckin - Run all pre-checkin validation checks
  • cargo xtask header-check - Check license headers in source files
  • cargo xtask header-fix - Fix missing license headers in source files

Examples

# Build the project

# Run tests

# Create a distribution
cargo xtask dist

# Format code
cargo xtask fmt

# Run clippy
cargo xtask clippy

# Build documentation

Development

The project is structured as a Cargo workspace with two main components:

  • openprot/ - The main application
  • xtask/ - Build automation scripts

The xtask workflow allows you to add custom build steps, automation, and project management tasks written in Rust, making them cross-platform and easy to maintain.

Requirements

  • Rust 1.70+ (2021 edition)
  • Cargo

No additional tools are required - everything is handled through Cargo and the xtask scripts.
