-//! Feishu/Lark Bot channel for IronClaw.
-//!
-//! This WASM component implements the channel interface for handling Feishu
-//! webhooks (Event Subscription v2.0) and sending messages back via the
-//! Feishu/Lark Bot API.
-//!
-//! # Features
-//!
-//! - Webhook-based message receiving (Event Subscription v2.0)
-//! - URL verification challenge handling
-//! - Private chat (DM) support
-//! - Group chat support with @mention triggering
-//! - Tenant access token management (app_id + app_secret exchange)
-//! - Supports both Feishu (open.feishu.cn) and Lark (open.larksuite.com)
-//!
-//! # Security
-//!
-//! - App credentials (app_id, app_secret) are injected by the host into
-//!   the config JSON during startup for token exchange
-//! - Bearer token for API calls is obtained via token exchange and cached
-//! - Verification token validated by host for webhook requests
