feat: initialize repo with NixOS and Home Manager configs

- Add .gitignore for common languages, tools, and OS/editor artifacts
- Configure .gitattributes for Git LFS (fonts, images, archives, ISOs)
- Add README with repo description
- Add flake.nix defining inputs and outputs for NixOS, Home Manager, and related modules
- Introduce home-manager configs:
  - Base home.nix with packages, services, and programs
  - Hyprland WM configuration (waybar, fuzzel, keybindings, theming)
  - Vim (nixvim) setup with LSP and plugins
  - Zsh setup with aliases, Oh My Zsh, clipboard helpers
  - Systemd user services (e.g., librespot)
- Add scripts (GPU monitor, RAM build helper, install automation)
- Add host configurations:
  - Nixbook (Apple laptop) with hardware, disko, and install script
  - Nixstation (desktop) with firewall, virtualization, Btrfs scrub timer
  - Nixtest (test VM) with QEMU + Alpine-based install test harness
  - Common modules (network, NVIDIA, rclone, screen, keychron, users)
- Include statix config for linting

+# My personal machines config files
+
+This repository contains declarative configurations for personal machines managed with NixOS flakes and Home Manager.  
+The setup is split into host-specific configurations, common reusable modules, and user-level home configurations.
+
+## Structure
+- **flake.nix** — entry point, defines inputs (nixpkgs, home-manager, nixvim, etc.) and system/home outputs.
+- **hosts/** — machine-specific system configurations.
+  - `Nixbook/` — laptop setup (Apple hardware, Hyprland, disk layout via disko).
+  - `Nixstation/` — desktop workstation (NVIDIA, virtualization, btrfs scrub, firewall).
+  - `Nixtest/` — minimal VM environment for testing with QEMU.
+  - `common/` — shared modules (users, keyboard, network, gpus, rclone, etc.).
+- **home-manager/** — user environment configurations.
+  - `home.nix` — main Home Manager entry for user packages and programs.
+  - `vim.nix`, `zsh.nix`, `gnome.nix`, `hyprland/` — modular desktop and tool configurations.
+  - `scripts/` — helper shell scripts (GPU monitor, RAM-disk builds, install helpers).
+
+## Usage
+### Build and switch system configuration
+
+```sh
+sudo nixos-rebuild switch --flake .#<hostname>
+````
+
+Example for Nixbook:
+
+```sh
+sudo nixos-rebuild switch --flake .#Nixbook
+```
+
+### Build and switch home configuration
+```sh
+home-manager switch --flake .#thiago@<hostname>
+```
+
+Example for Nixstation:
+```sh
+home-manager switch --flake .#thiago@Nixstation
+```
+
+### Installation
+For new installs, use the provided install scripts:
+* **hosts/Nixbook/scripts/install.sh** — remote installation with `nixos-anywhere`.
+* **hosts/Nixtest/scripts/install\_test.sh** — bootstraps a test VM with Alpine + QEMU.
+
+### Scripts
+Some helper scripts are included:
+* `lsgpu.sh` — monitor NVIDIA GPUs in terminal.
+* `nixstation-home-ram-build.sh` — run `home-manager` builds in a RAM disk.
+* Install scripts under each host as described above.
+
+## TODOs:
+* Device identifiers (disk paths, GPU PCI IDs, monitor names) are currently hardcoded and may need modification on different hardware.
+* Find a good secret management system/process
