fix(skills): 去除束缚 Agent 自主判断的机械数字策略 (#58)

## 摘要 / Summary

### 中文

去除技能里束缚执行 Agent 自主判断的**机械数字策略**：create 需求收集的「每轮最多问 2 个」、discover
排序的「最多展示 5 个候选」。改为交由 Agent 按情况自主把握追问节奏与展示数量，保留「别让用户负担 /
别一次刷屏」的原则意图——把控制权交还给判断力更强的执行者，而非用固定上限约束。create 2.5.3 / discover
2.6.3，manifest 1.2.14，中英双份同步、重算 source_hash（validate-i18n 通过）。

### English

Remove mechanical numeric limits that constrain the executing Agent's
judgment: create's "at most 2 questions per turn" and discover's "show
at most 5 candidates". Both become "the Agent decides the pacing/count
by situation", keeping the principle intent (don't burden the user /
don't flood the screen) while handing control back to the more capable
executor instead of a fixed cap. create 2.5.3 / discover 2.6.3, manifest
1.2.14, both locales synced, hashes recomputed (validate-i18n passes).
