refactor: drop disko, simplify inputs, centralize fuse/rclone, bump state versions

- Remove disko everywhere:
  - Delete hosts/Nixbook/disko.nix and hosts/Nixtest/disko.nix
  - Drop disko input, modules, and disko-install app
  - Update README to remove disko mention
- Simplify flake inputs:
  - Use nixpkgs = nixos-unstable only
  - Home Manager -> master (follows nixpkgs)
  - Remove nixpkgs-unstable and vscode-extensions
  - Pass allowUnfree via specialArgs
- Centralize storage tools:
  - Add fuse3 and rclone to hosts/common/default.nix
  - Remove hosts/common/rclone.nix and screen.nix
  - Add user thiago to "fuse" group
  - Drop per-host rclone packages
- NVIDIA module:
  - Use pkgs.linuxPackages.nvidiaPackages.latest (no unstable import)
  - Keep nvidiaSettings=true, open=false
  - Remove sunshine service block
- Hosts:
  - Nixstation: remove Hyprland block, zramSwap 30% -> 25%
  - Clean hardware-configuration args
- Versions:
  - system.stateVersion: 24.05 -> 25.11 (Nixstation)
  - home.stateVersion: 24.05 -> 25.11
- README: adjust Nixbook and common modules descriptions
