Before: the panel stayed. After: it is put away and the viewport gets the room.

Situation

Turing Sim's Content panel, the example and asset browser, opens with Cmd-Shift-E. Once open, the same shortcut did nothing, so it took several clicks to get the viewport's room back. The bottom panels' top edge could only be dragged down: with no central widget, Qt had no room above to grow into. Two shortcuts had also leaked out of their panels: Ctrl-Return in the chat input sent a message from anywhere, and Return or Cmd-F in Content acted from fields in other panels.

Task

Make Content behave like a drawer, let the bottom edge move both ways, and keep each panel's shortcuts inside that panel.

Action

1. Cmd-Shift-E toggles. With the Content panel in view, the shortcut puts it away; pressed again, it reopens at the height it was put away at.
2. The bottom edge drags both ways. Dragging it resizes the panels on both sides, and a taller window gives its height to the viewport row instead of the bottom panels.
3. A short Content dock stays usable. Its panes scroll and its footer hides below a minimum height.
4. Shortcuts stay local. PySide6 silently ignores QShortcut(context=...) when a slot is passed, which had left them window-wide. They now set their context explicitly.

The commit was tested in isolation: 80 passed and 6 native docking tests skipped offscreen.

Result

The captures press the shortcut with Content open. The old version keeps the panel; the new one puts it away. The demo opens and closes it twice. A native check for the shortcuts was added (verify_panel_key_focus.py) but was not run in this session.

⌘⇧E 现在可以像抽屉一样打开和收起 Content 面板。

背景

Turing Sim 的 Content 面板（示例和资产浏览器）用 ⌘⇧E 打开。打开之后再按同一个快捷键没有任何反应，要点好几下才能把视口的空间要回来。底部面板的上边缘只能往下拖：窗口没有中央控件，Qt 在上方没有可以扩展的空间。还有两个快捷键越出了自己的面板：聊天输入框的 Ctrl-Return 在任何地方都会发送消息，Content 里的 Return 和 ⌘F 会在其他面板的输入框里触发。

目标与难点

让 Content 像抽屉一样开关，让底部边缘可以上下拖，并让每个面板的快捷键只在自己面板里生效。

解决思路与行动

1. ⌘⇧E 可以开关。 Content 面板可见时按下会收起；再按一次，会按收起时的高度重新打开。
2. 底部边缘可以上下拖。 拖动时同时调整上下两侧面板的大小；窗口变高时，多出的高度给视口那一行，而不是底部面板。
3. 矮的 Content 面板依然可用。 窗格可以滚动，低于最小高度时页脚会隐藏。
4. 快捷键只在本面板生效。 传入 slot 时 PySide6 会悄悄忽略 QShortcut(context=...)，导致这些快捷键变成全窗口生效。现在改为显式设置 context。

这个 commit 单独测试：80 项通过，6 项原生停靠测试在离屏模式下跳过。

结果与下一步

截图里都是在 Content 打开时按下快捷键。旧版本面板还在；新版本面板被收起了。动图里开关了两次。这个 commit 还加了一个原生窗口里的快捷键检查脚本（verify_panel_key_focus.py），本次会话没有运行它。
