feat: add hibernado plugin

Add Hibernado to Plugin Store

Hibernado is a decky plugin that lets Steam Deck hibernate or suspend-then-hibernate from within game mode/gamescope session.

On first plugin install, user must click the setup button, where a few things like swapfile creation, symlink creation, some systemd helpers etc. The bulk of the implementation here mirrors the guide from: Steam Deck Hibernation Guide by nazar256 (credited in readme and hibernation-helper.sh script), with some key changes to fix things from their guide like boot count incrementing incorrectly after multiple successful hibernate and resumes.

Once all is configured, user can choose either manually executing hibernation, or sleep then hibernate from buttons inside the plugin, with a drop down to choose the time between suspend and hibernate (default 60 min).

Additionally they can toggle on a power button override, where they can set the deck's power button to either hibernate or suspend > hibernate on button press. Suspend-then-hibernate mirrors the manual button setting for span between sleep and hibernate setting.

If user presses "remove setup" button at the bottom of the plugin, or on the even the plugin is uninstalled or reinstalled through decky, all the above setup files and symlinks are removed and undone, so the plugin is sure to "clean up after itself" and be a good citizen.

Per our Discord discussions, this has been fully re-worked from my earlier version that relied on system file unlocking. I believe the current implementation should be safe and compliant with decky store policy. Looking forward to your review!

I'm using BazziteOS on my Steam Deck (I'm using it for specific reasons that aren't relevant here). And when I click on setup in the plugin, it shows a "Setup Fail" error.

@atiladpribeiro yes, this solely works on steam os due to specific quirks, for bazzite hhd has its own hibernate option!
