dsh-feishu-integration: Bidirectional Integration of DeepSeek Harness and Feishu

The DeepSeek Harness (DSH) Feishu integration plugin is designed to address the issue that backend services or web clients cannot interact via IM. It provides features such as conversation summary push notifications, reply routing, persistent session continuation, and multi-domain support. After installation, it must be linked on the settings page, and inbound takeover must be enabled to control replies. The plugin supports CLI management and data migration, and includes reliability mechanisms such as retries, idempotency, and secure storage. It is community-maintained and released under the MIT license.
