- Introduced comprehensive stepper motor control implementation, including hardware-accelerated PIO-based and GPIO-based backends for RP2040. - Registered Klipper-compatible commands: `config_stepper`, `queue_step`, `set_next_step_dir`, `reset_step_clock`, and others for motion control. - Developed stepper command handlers in `core/stepper_commands.go` with support for precise timing, multi-axis coordination, and queue-based motion scheduling. - Updated RP2040 initialization (`main.go`) to register stepper drivers and backends automatically. - Added `stepper.md`, a detailed guide covering architecture, performance benchmarks, PIO assembly for step generation, configuration examples, and testing procedures. - Ensured protocol compatibility with Klipper for advanced host-based planning and motion execution.
