fix(chat): 前端审计修复——预览契约改HTML/状态机统一/进度错误持久化/chat_state.js抽取

- app.py: /result/preview 返回渲染 HTML(HTMLResponse) 而非 {html} JSON；新增 /chat_state.js 静态路由；预览缺失返回 404(RESULT_NOT_FOUND) - chat.html: currentProject 统一为 draftProject；新会话继承已选项目(§4.2)；上传区显隐/类型映射/抽屉脏检测改用 GenesisState；loadSession 按 role 渲染 progress/error；加 h1 标题 - chat_state.js(新): 抽取 autoBindProject/shouldHideUploadSelect/resolveUploadType/computeDrawerSnapshot/isDrawerDirty/buildWelcome 纯函数(U+1 分隔符) - agent.py: 新增 _persist_progress/_store_error，进度与错误以 role 入库(重载可见) - 测试: test_chat_state.js(11 passed) + test_frontend_audit_fixes.py(5) + 修正 test_server_api 旧 JSON 契约断言；全量 pytest 568 passed / 99.06%
