He-Pin opened a new issue, #3219:
URL: https://github.com/apache/pekko/issues/3219
### Motivation
`StubbedActorContext.scheduleOnce` 返回的 `Cancellable` 处于预取消状态：`cancel()` 返回
`false`（表示取消失败），`isCancelled` 返回 `true`（表示已取消）。这使得测试中无法正确验证定时器的取消行为。
### 当前代码行为
`StubbedActorContext.scala` 中：
```scala
// StubbedActorContext.scala:162-166
override def scheduleOnce(delay: FiniteDuration, runnable: Runnable)(
implicit executor: ExecutionContext): classic.Cancellable =
new classic.Cancellable {
def cancel(): Boolean = false // 取消失败
def isCancelled: Boolean = true // 但声称已取消
}
```
`cancel()` 返回 `false` 表示"取消操作未成功"，而 `isCancelled` 返回 `true` 表示"已被取消"，两者语义矛盾。
### 预期行为
返回的 `Cancellable` 应该语义一致：
- 如果定时器可取消：`cancel()` 返回 `true`，`isCancelled` 变为 `true`
- 如果定时器已执行：`cancel()` 返回 `false`，`isCancelled` 为 `false`
### 代码证据
-
`actor-testkit-typed/src/main/scala/org/apache/pekko/actor/testkit/typed/internal/StubbedActorContext.scala:162-166`
— 预取消的 Cancellable 实现
### 复现方式
```scala
val context = new StubbedActorContext[String](self = TestProbe().ref, system
= system)
val cancellable = context.scheduleOnce(1.second, () => ())
assert(cancellable.cancel() == false) // 取消失败
assert(cancellable.isCancelled == true) // 但已取消？矛盾
```
### 影响范围
- 模块：`pekko-actor-testkit-typed`
- 影响使用 BehaviorTestKit 测试定时器取消逻辑的代码
- 测试可能因语义矛盾而无法正确验证定时器行为
