refactor: fix statix linting warnings and remove unused Hyprland profile

- Add .envrc with direnv integration for automatic nix develop environment
  * Enables nix flakes and experimental features automatically
  * Allows pre-commit hooks to run properly with full environment

- Fix nix develop shellHook to not hang when using --command flag
  * Only exec zsh if running interactively (not with --command)
  * Prevents pre-commit hooks from hanging in CI/non-interactive mode

- Remove unused Hyprland profile and desktop configurations
  * Delete common/profiles/hyprland.nix and wallpapers
  * Remove desktop-x86 and desktop-arm from flake.nix

- Fix all statix linting warnings:
  * Merge repeated attribute set keys into single blocks
    - programs.* → programs = { ... }
    - home.file.* → home.file = { ... }
    - environment.* → environment = { ... }
    - system.* → system = { ... }
  * Replace empty patterns { ... }: with _:
  * Use inherit syntax where appropriate (username, isLinux, isDarwin)

- Update pre-commit flake-check hook to explicitly enable experimental features

All pre-commit hooks now pass cleanly.
