feat: add Feishu/Lark WASM channel plugin (#1110)

part of #1046 - Implement Feishu Event Subscription v2.0 webhook (URL verification + im.message.receive_v1) - Token exchange via workspace-cached app credentials with 5-min pre-expiry refresh - Host-side secret injection into config JSON (setup.rs) so WASM can access app_id/app_secret without env vars - Reply and broadcast via /open-apis/im/v1/messages - Enforce allow_from user filtering in message handler - DM pairing flow with owner_id restriction - Dual API base support: open.feishu.cn (Feishu) / open.larksuite.com (Lark) - Registry manifest, bundled channel entry, messaging bundle integration - Strip raw config_json debug log to prevent secret leakage
