* fix(linux): prevent startup panic from unrealized capsule GDK window | fix(linux): 修复胶囊窗口因 GDK 未实例化导致的启动崩溃
On Linux X11, when the capsule window is created with `visible: false` +
`transparent: true` in tauri.conf.json, its underlying GDK window is never
realized. The subsequent call to `capsule.set_ignore_cursor_events(true)`
triggers a panic inside tao's Linux event loop (event_loop.rs:457) because
`window.window().unwrap()` returns `None` for an unrealized GDK window.
The fix follows the same approach as voicebox PR#837 (PhamBit):
force GDK window realization before calling set_ignore_cursor_events, by
first moving the window off-screen and calling show(). The window is then
repositioned correctly by the existing position_capsule_bottom_center()
call and hidden as normal.

在 Linux X11 上，tauri.conf.json 中定义的 capsule 窗口设置了
visible: false + transparent: true，导致其底层 GDK 窗口从未被实例化。
随后调用 capsule.set_ignore_cursor_events(true) 时，tao 的 Linux 事件循环
(event_loop.rs:457) 因 window.window().unwrap() 返回 None 而 panic 崩溃。
修复方法参考 voicebox PR#837：在设置鼠标穿透前先将窗口移出屏幕并
调用 show() 强制 GDK 实例化，后续由原有的 position_capsule_bottom_center()
重新定位并隐藏。
