首页加回做方案入口

master 的直连 Codex 改造把 HomeAgentMode 和「做游戏 / 做素材 / 做方案」模式栏
整个删了，合并后 startMode 在前端没有 planning 的来源，只能写死 direct-build。
立项策划链路的后端、prompt、澄清卡、审批卡都还在，但从首页够不着，CI 上
home.suite.ts 的两条 routes 做方案 用例也因此找不到按钮而挂。

不把三选一搬回来（那是 master 主动收掉的产品形态），只在输入框工具栏加一个
「做方案」开关：选中时 startMode 走 planning、提交按钮文案切成「进入立项策划」、
占位文案换成方案口径；不选中时与 master 的直连默认完全一致。
createHomeDraft / createHomeDraftAutomatically 改为由调用方传 startMode，
删掉 HOME_DRAFT_START_MODE 这个占位常量。
