Automatically Select Inference Modes for DeepSeek Harness Using dsh-router-standard

`dsh-router-standard` is a DSH session preset maintained by yjh051108 (MIT License, v0.2.0). It selects a mode based on the task before the first round of requests: the `standard` mode restores the RL interface and follows the think-act loop, while the `spec` mode enables deep thinking; behind this are the three bands of `spec/mixed/react`. It supports persona, first-round tool injection and agent parameter tuning. The directory command is `dsh plugin add github:yjh051108/dsh-router-standard`, and it needs to be copied to `~/.dsh/.agent-presets/` to enable. The community directory is not an official store, and plugins run with the current DSH permissions.
