Code Review
This pull request implements a distributed communication framework for the A2A3 platform, supporting HCCL hardware and shared-memory simulation backends. It introduces a per-chip bootstrap mechanism for communicator initialization, device memory allocation, and data staging, supported by the new DistChipBootstrapChannel. The Worker class and CodeRunner utility were refactored to handle level 3 distributed execution and process lifecycle management, with corresponding extensions to the Python bindings and C API. Feedback identifies a breaking change in the task.orch function signature and suggests optimizing performance by moving a module import out of a loop in the bootstrap method. Comprehensive unit tests for the bootstrap channel and worker API are also included.

The signature of the orchestrator function task.orch has been changed from orch(orchestrator, args) to orch(worker, args). This is a significant breaking change that should be documented in the pull request description. While the new API of calling methods on the worker instance is an improvement, the lack of documentation for this change can cause issues for users of this class.

The import ctypes as _ct statement is inside a loop. While this works, it's inefficient to re-import the module on every iteration. For better performance and code style, please move this import to the top of the bootstrap method (e.g., on line 304).
