fix: support Space key to toggle panel and prevent default scroll - #457
Pressing Space on an enabled collapse header now toggles its panel and prevents page scrolling. Disabled headers ignore keyboard activation, and key events from nested controls in extra keep their own default action without toggling the panel.
Testing
Space activation and nested-button regressions; the nested-button case failed before the guard.
Full native suite: 100 tests and 1 snapshot passed; ESLint passed.
TypeScript still reports four existing obsolete Jest matcher type errors; the same errors were reproduced with the original test file.
The PR is functionally sound, with a small regression-coverage gap for Enter events from nested extra controls.

只处理标题触发元素自身的 Space 键事件。
当 extra 包含获得焦点的按钮时，按钮的 Space 键事件会冒泡到标题容器。此处调用 preventDefault() 并切换面板，会取消按钮的默认操作。请在处理前确认 e.target === e.currentTarget，并增加嵌套按钮的回归测试。WAI-ARIA Accordion Pattern 也将 Space 键切换限定于焦点位于折叠标题的情况。(w3.org)

src/Panel.tsx 将 onKeyDown 绑定到包含额外按钮的头部。修改前，额外按钮上的 Enter 事件会冒泡并调用 onItemClick，从而切换面板。当前测试只覆盖 Space，无法检测 Enter 路径的回归。
