feat(window-manager): implement in-app achievement notifications for …

[Moyasee]

…Linux

• Added sendAchievementToFocusedWindow method to handle achievement notifications within the app on Linux/Wayland, where standalone overlays are not supported.
• Updated mergeAchievements to utilize the new method for in-app notifications.
• Introduced IPC listener for in-app achievement notifications in the preload script.
• Enhanced the renderer to display achievement notifications using the new overlay component.

This update improves user experience by providing timely feedback on achievements directly within the application interface.

Fill in the PR content:

update for linux users
recent electron update killed the custom notification window which is causing it to spawn directly in the center and not on top of all apps

this PR fixes this issue doing the following:

• Display the custom notification window inside of the Hydra main/big-picture window
• Display the native OS notification toast when other window(game) is focused
