mctp: wire real I2C transport into server loop (Phase 6 Step 3)

Replace NoopSender with I2cSender<IpcI2cClient> and add inbound
slave-notification handling to the MCTP server main loop.

Changes:
- Add imports: IpcI2cClient, I2cTargetClient, I2cSender, MctpI2cReceiver,
  BusIndex, TargetMessage; add OWN_EID and OWN_I2C_ADDR constants
- Register slave notification via register_notification(BUS_0) at startup
- Replace single object_wait(MCTP) loop with a WaitGroup that multiplexes
  two sources:
    user_data=0: IPC from a client (MCTP channel READABLE) -> dispatch
    user_data=1: I2C slave notification (I2C channel USER) ->
                 get_pending_messages -> MctpI2cReceiver::decode ->
                 server.inbound()
- Remove NoopSender struct and its Sender impl

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

# Format code
cargo xtask fmt

# Run clippy

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.
