hot-reload 3

Live-reload upgraded DeepSeek Harness (dsh) plugins without restarting dsh — the running plugin is swapped in place, and a reload that fails rolls back to the working old version and asks for a manual restart.

Runtime hot-swap for DeepSeek Harness: hot enable/disable/restart Cordis plugins and auto hot-mount bundles from the Web GUI — no dsh restart.

Hot-toggle any installed plugin in DeepSeek Harness from the Web settings — instant apply, no restart, persisted. 在 DSH 设置页一键热启用/停用任意插件，立即生效、无需重启、状态持久化。
