Better window creation/switch detection for Raycast/Alfred

[kanghengliu]

As indicated in this thread, with current implementation, apps that do not signal front application changed like Raycast/Alfred(no compatibility mode) do not get detected in window switching.

It's not really a major problem in alfred, since after invoking alfred bar, typing will start in insert mode;

However in Raycast, svim will start as whichever mode that's last used in it.

It would be great if either:

• Detect window switching with more robust methods.
• Detect window destroyed event to reinitialize raycast bar's vim buffer to start at insert mode

For the first solution, this issue in KindaVim mentions using "other nails and hammers" method to detect new windows. Sadly KV is closed source so we have little idea as to which.
