Step 3. Describe the issue

Description:
Firstly
A lockscreen crash occurs in the end-4/dots-hyprland setup when the wallpaper switching script (switchwall.sh) is triggered while the system is offline. This results in an invalid or truncated path bein
saved to the configuration (specifically ending in a dot . instead of a file extension). Consequently, when the lockscreen app (Quickshell or Hyprlock) attempts to load this invalid image path, it fails a
displays the "Oopsie daisy, it looks like your lockscreen app died" error.

Steps to Reproduce:
(Ensure "lock": { "launchOnStartup": true } is enabled in ~/.config/illogical-impulse/config.json.)

1. Disconnect the system from the internet.
2. Trigger the wallpaper switch (e.g., via the "Random Wallpaper" button/keybind which calls ~/.config/quickshell/ii/scripts/colors/switchwall.sh).
3. Observe that the script fails to download/create the image correctly due to the lack of connection.
4. Check ~/.config/illogical-impulse/config.json. The wallpaperPath entry will likely be truncated (e.g., /path/to/random_wallpaper.).
5. Lock the screen (manually or wait for hypridle timeout).

Actual Behavior:
The lockscreen fails to render the background because the file path is invalid, leading to a crash loop or the "Lockscreen app died" error screen. The user is stuck on a black screen or the error message
until the config is manually fixed.

Technical Root Cause:
The switchwall.sh script (or the process it calls) updates the wallpaperPath in config.json without verifying if the target image file was successfully generated or downloaded. When hypridle trigger
the lockscreen, the lockscreen application attempts to read this non-existent file path and crashes.

Suggested Fix:
The switchwall.sh script should verify if the new wallpaper file exists and is a valid image before updating the wallpaperPath in config.json. If the download or generation fails (e.g., due to no
internet), it should abort the config update and potentially notify the user, retaining the previous valid wallpaper.
