nyaterm-bridge: Let AI execute commands in the real NyaTerm terminal

The client-side DSH plugin maintained by visualcjy enables AI to execute commands within NyaTerm's real terminal sessions, reusing configured groups, jump hosts, and connections, while restricting available groups, hosts, and connections via a workspace-level allowlist. Based on plugin documentation, the article explains its division of labor with dsh-remote, the installation command `dsh plugin --profile web add github:visualcjy/nyaterm-bridge`, the `nt_*` toolset, the three-tier permission model, the two allowlist configuration methods (GUI and JSON), the MCP program location resolution order, cross-platform behavior, and known limitations such as host details hiding, out-of-band execution, and the lack of a session close tool.
