chore(hyprland): delete orphan config files + share-picker dir

Six unreferenced files surfaced under features/desktop/hyprland/config/
during the Pillar 8 sweep:

- `looknfeel.conf` and `autostart.conf` were deployed to ~/.config/hypr/
  but never sourced by nomarchy.conf. The substantive versions live in
  core/home/config/nomarchy/default/hypr/ and are sourced from there.
  Removed the deployment lines in features/desktop/hyprland/default.nix
  alongside the file deletes.
- `hyprlock.conf`, `hyprsunset.conf`, `xdph.conf` weren't deployed at
  all and weren't referenced anywhere. Pure leftovers.

The entire `features/desktop/hyprland-preview-share-picker/` directory
was also orphan: no `default.nix`, no Nix module imports the
`config.yaml`. Only mention was inside the (now-deleted) `xdph.conf`.
Deleted the directory.

No behavioral change — these files weren't being used. Just removes
dead surface that confuses contributors looking for the "real" config
location.
