docs(todo): update invariant catalog for parallel active items

The package-invariant catalog Note still described dsh-tool-todo as
enforcing at most one active item; align the bilingual pair with the
implemented invariant set (unique trimmed items, closed statuses) and
re-record the pairing hashes.

 Session-backed companions validate existing durable events when they load, using the prefix preceding each candidate where the relationship depends on event order. Other checks observe the authoritative live event boundary or mutable service result. Validation runs before publication where accepting an invalid event would otherwise commit bad state.

 基于 session 的 companion 在加载时验证已有持久化事件；关系依赖事件顺序时，会使用每个候选事件之前的事件前缀。其他检查观测权威 live event 边界或可变服务结果。如果接受无效事件会提交错误状态，验证就在发布前执行。
