* fix(spotlight): fix empty results on restoring last file search query
- When "remember last query" is enabled and the last query is file search, it shows "no results" until the query is manually modified in full launcher mode.
* fix(spotlight): properly restore last selected mode(tab) when enabled in full launcher mode
* fix(spotlight): allow file trigger in plugins mode(tab)
* fix(spotlight): restore previous mode when clearing '/' file search prefix
When the '/' prefix is removed from the query, the controller now correctly reverts to the previous mode instead of remaining stuck in "files" mode.
* fix(spotlight): code review fix
