dsh-fun-turn-status: Replace the "Deep diving..." status copy during DSH task execution.

The DeepSeek Harness (DSH) plugin "dsh-fun-turn-status" replaces the "Deep diving..." status during task execution with humorous messages that randomly rotate every 30 seconds. Users can set custom messages in the configuration (up to 50), and changes take effect immediately without restarting. Designed to reduce the tedium of waiting, the plugin suits users who value a playful interface. The source code is available on GitHub.
