s16中LLM只能看到有一个workflow工具，不知道有"review-changes"等工作流

review-changes等具体工作流的名称并没有注册到宿主机中，所以LLM在决策的时候，几乎不可能输出工具调用（workflow，”review-changes“）

Hi, I traced this in the current s16 runtime. WORKFLOWS contains trusted metadata such as each workflow's name and description, but WORKFLOW_TOOL exposes name only as an unconstrained string. As a result, the model sees the generic Workflow tool but not review-changes or its purpose.

Would you accept a small PR that derives the tool's allowed names and a concise catalog from WORKFLOWS, with deterministic tests and synchronized EN/ZH/JA documentation? It would keep the run_workflow(name, args, resume_from_run_id) call shape unchanged and would not add dynamic user workflows, a new discovery tool, or retrieval infrastructure.

Is this direction aligned with the s16 teaching design, or is another approach already planned? I used Codex for initial code analysis and will review and stand behind any patch.
