feat(roundtable): 第一步识别出的意图支持手动编辑并保存

「当前意图摘要」卡新增编辑态：核心目标(必填)、约束、关键假设(可增删列表)，
保存后由 useStep1Intent.updateIntentReady 覆盖权威 intentReady，下游(Step 2
种子消息 buildInitialIntent、侧栏摘要卡、step2Locked)随之生效，并落草稿持久化。

持久化用「计数 + effect」触发 handleManualSave，避免 enqueueSave 闭包在 setState
flush 前读到旧意图的竞态(与 step2/step3 计数触发器同构)。聊天气泡内的绿色意图卡
保持为历史记录，右侧「当前意图摘要」为可编辑的当前值。
