Module channels 

Channel subsystem for messaging platform integrations.

This module provides the multi-channel messaging infrastructure that connects Construct to external platforms. Each channel implements the Channel trait defined in traits, which provides a uniform interface for sending messages, listening for incoming messages, health checking, and typing indicators.

Channels are instantiated by start_channels based on the runtime configuration. The subsystem manages per-sender conversation history, concurrent message processing with configurable parallelism, and exponential-backoff reconnection for resilience.

Extension

To add a new channel, implement Channel in a new submodule and wire it into start_channels. See AGENTS.md §7.2 for the full change playbook.
