* feat: rewrite search module (WIP)
There are some caveats because it is a WIP
- Messages are not i18n yet
- Missing placeholder suggestion thumbnail
- Only REST mode works
- Missing greeting message when there is no search query
- Code might look like a mess (I learned JS not long ago)
* refactor: remove old search module
* feat: clean up search suggestion styles
* feat: hide overflow for suggestion text
* feat: add action API and various cleanup
* feat: re-add abort controller
* feat: add message support and tweaks
* feat: use virtual config instead of ResourceLoader hook
