[Feature request] Allow configurable timeout for restartAfterInstall in OTA updates

[BangDori]

Is your feature request related to a problem? Please describe.

Currently, the restartAfterInstall option in OTA updates has a hardcoded timeout of 300ms before restarting the app. - Link

This makes it feel like the app restarts immediately after the update is applied, preventing a smooth transition. (Maybe it's just me who feels this way 😓)

Describe the solution you'd like

It would be helpful to allow developers to configure the timeout delay before the restart.

Describe alternatives you've considered

One approach could be to keep the default 300ms timeout but allow developers to override it, like:

setTimeout(() => {
  // ...
}, option.restartDelay ?? 300);
