[TODO] Implement Start/Stop functionality for video capture on keypress

[0Ky]

Currently, the app is hardcoded to capture only for 10 seconds when you click the capture video menu item from the system tray: https://github.com/0Ky/screenclip/blob/3d730cce88d807f061cf6117835975f61fa1ccd2/src-tauri/src/main.rs#L65

Instead, video capture should begin after a certain keypress, and continue capturing until the same key is pressed again.
