What

Remove thread-id argument from uwf thread fork.

Why

CAS 节点自包含，从 step-hash 就能回溯到 StartNode，不需要指定 thread-id。

Changes

cli.ts — fork 只接受 <step-hash> 一个参数
thread.ts — 删除链遍历验证，改为直接检查节点类型（StartNode/StepNode）
types.ts — ThreadForkOutput.forkedFrom 移除 thread 字段

Ref

Refs #342

Remove thread-id argument — CAS node is self-contained, no need to
specify which thread it belongs to. Just verify the hash is a valid
StartNode or StepNode.

LGTM ✅ CAS 天然可寻址，不需要 thread-id 验证归属，直接用 hash fork 就对了。
