dsh-free-ai: Plugin Introduction - Connecting Free Model Channels to DSH

`jianghuai24/dsh-free-ai` is a DSH model inference plugin that registers 13 free model channels (CodeArts, WorkBuddy, LobsterAI, Qoder, TRAE, Cline, Loomy, Raccoon, MiniMax Code, ZCode, Gemini, etc.) as DSH providers. It features built-in browser login, multi-account pool rotation, daily check-in for points, a model blacklist (dead-model-store), and a local OpenAI-compatible gateway. The article introduces the repetitive work on the adapter layer it addresses, the installation command `dsh plugin --profile desktop add link:<repository directory>`, the conflict with `dsh-our-free-model` that prevents simultaneous usage, the requirement for a self-provided OAuth client for the Gemini channel, and precautions such as checking the source code and license before installation.
