dsh-hitchfin: Using WorkBuddy, Qoder, and Trae subscription models in DSH

dsh-hitchfin is a DSH model inference plugin maintained by LuckyOneTwoThree (v0.4.0, MIT). It integrates WorkBuddy CN, Qoder CN, and Trae CN into DeepSeek Harness via official login flows, supporting multi-account session-based failover, per-account HTTP(S) proxies, default free-model-only filtering, and model visibility management. Installation can be performed via the plugin market, `dsh plugin add` in npm, or by local npm pack and install. Credentials are stored locally in DSH, with no account sharing or quota bypassing. It is suitable for developers who already hold subscriptions from various channels and wish to select models uniformly in DSH while requiring disaster recovery.
