[CI] chore: update flake

* feat: add wallpaper post-hook for dynamic theming

Adds support for running custom shell commands after wallpaper changes
via the `wallpaper.postHook` config option in `~/.config/caelestia/cli.json`.

The wallpaper path is made available to the hook via the $WALLPAPER_PATH
environment variable. This enables integration with tools like `matugen`
or `pywal` for dynamic theming based on wallpaper colors.

The hook runs after apply_colours() in set_wallpaper(), ensuring it
executes for all wallpaper change methods (UI, IPC, and direct CLI).

* Replaced comment in example config with no-op command
