fix(persona-sim): 演出脚本字段不全导致整页崩溃

[qegj567-cloud]

LLM 偶尔生成的 app beat 缺嵌套数组（如 view:'chat' 却无 chat.lines）， 渲染到 .map 时整页崩（Safari 报 undefined is not an object）。 新增 normalizeScript 把 chat.lines / search.queries / notes.items / browser.tabs / compose.drafts 统一兜底成数组，parseScript 与生活记录 重播两条路径都过一遍，覆盖新生成脚本和旧损坏快照。

Code Review

This pull request introduces a normalizeScript helper function in apps/PersonaSim.tsx to ensure nested arrays within the simulation script's app beats are properly initialized, preventing rendering crashes when the LLM output is incomplete. The feedback highlights a critical issue where normalizeScript mutates its input in-place, which violates React's immutability principles when applied to props, and notes a potential TypeError if the input is null. It is recommended to add a null check and deep-clone the script object before modifying it.

在 normalizeScript 中，直接对传入的 s 进行修改（in-place mutation）会带来潜在的 React 渲染和状态管理问题。

当重播时，sim.script 作为 React 组件的 Prop 传入，直接修改它会违反 React 的不可变性（Immutability）原则，可能导致父组件状态被污染或组件未能正确触发重渲染。

此外，如果 s 为 null 或 undefined（例如 JSON.parse 解析失败返回 null），直接读取 s.beats 会抛出 TypeError。

建议在函数开头增加空值校验，并使用 JSON.parse(JSON.stringify(s)) 进行深拷贝，以确保不污染原始数据。

function normalizeScript(s: SimScript): SimScript {
    if (!s || !Array.isArray(s.beats)) return s;
    // 避免直接修改 React props/state，先进行深拷贝
    const cloned = JSON.parse(JSON.stringify(s)) as SimScript;
    for (const b of cloned.beats) {
        const a = b?.app;
        if (!a) continue;
        if (a.chat && !Array.isArray(a.chat.lines)) a.chat.lines = [];
        if (a.search && !Array.isArray(a.search.queries)) a.search.queries = [];
        if (a.notes && !Array.isArray(a.notes.items)) a.notes.items = [];
        if (a.browser && !Array.isArray(a.browser.tabs)) a.browser.tabs = [];
        if (a.compose && !Array.isArray(a.compose.drafts)) a.compose.drafts = [];
    }
    return cloned;
}
