refactor(form): 使用 getter 访问 props 字段并补充单元测试
- formState 中与 props 对应的字段改用 getter，避免 props 与 formState 之间的同步中间态 - 完善 extendState 同步段的响应式追踪说明注释 - 新增 Form.extra.spec.ts 覆盖 isCompare 模式与 config 变化场景

/**
|
||||
* formState 实现说明：
|
||||
*
|
||||
* 1. 与 props 直接对应的字段（config / initValues / lastValues / isCompare / parentValues /
|
||||
* keyProp / popperClass）使用「访问器（getter）」定义，每次读取都会回到 `props.xxx`
|
||||
* 取最新值，不存在「props 变了但 formState 还没同步过来」的中间态。
|
||||
*
|
||||
* 2. `values` / `lastValuesProcessed` 是 ref，Vue 的 `reactive` 会自动解包，因此每次
|
||||
* 访问 `formState.values` / `formState.lastValuesProcessed` 也都是当前 ref 值。
|
||||
*
|
||||
* 3. `extendState` 注入的字段在下方的 `watchEffect` 中合并到 `formState`：
|
||||
* - data 描述符（普通字段）通过 `formState[key] = value` 写入，走 reactive proxy 的
|
||||
* set，触发依赖通知；`extendState` 同步段读到的响应式数据变化时会自动重跑，
|
||||
* 把最新值刷进 formState。
|
||||
* - accessor 描述符（`{ get stage() { return ... } }`）按原样写入，调用方可以控制
|
||||
* 读时求值，每次读取都会重新执行 getter。

* - data 描述符：通过 `formState[key] = value` 走 reactive proxy 的 set，

* 触发依赖通知；与旧版「逐项赋值」语义完全等价。
|

* - accessor 描述符（`{ get stage() {...} }`）按原样写入 formState，调用方
|
||||
* 可以自行控制读时求值；强制 `configurable: true` 以便下一次重跑可再 define。
