dsh-feishu-task-recorder: Two-Way Sync Between Feishu Message Polling and Task Board

The `dsh-feishu-task-recorder` plugin is designed to address the pain point of converting Feishu chat records into actionable task lists in DeepSeek Harness (DSH). It includes server-side and browser-side components, and supports scheduled polling, message deduplication, and AI/manual task extraction. It provides two-way synchronization between the floating panel and the task board, and supports full task review and status transitions (pending, judgment, completed) via command-line tools. The plugin offers comprehensive configuration options and a secure sandbox mechanism, and can automatically manage `lark-cli` tokens to ensure efficient and secure task processing.
