Zephrynis 10f0bc388d Initial NixOS flake-based multi-host setup

Add a NixOS system configuration using flakes, supporting multiple hosts (desktop, laptop, my-machine) with shared and per-host settings. Includes Home Manager integration, user-level and system-level package management, and example hardware configuration placeholders. Provides a README with setup instructions and a .gitignore for common Nix and editor artifacts.

NixOS System Configuration

This is a NixOS flake configuration for managing your system setup, ricing, and applications across multiple devices.

Initial Setup

Generate hardware configuration on your NixOS machine:
```
nixos-generate-config --show-hardware-config > hardware-configuration.nix
```
Copy the output to hosts/my-machine/hardware-configuration.nix
Update configuration files:
- Change my-machine to your actual hostname throughout the files
- Update yourusername to your actual username
- Adjust timezone, locale, and other personal settings
- Choose your desktop environment / window manager
Update flake inputs:
```
nix flake update
```

Build and switch to the new configuration:

sudo nixos-rebuild switch --flake .#my-machine

Adding a New Machine

Create a new directory under hosts/ with your machine's hostname
Generate and add the hardware configuration
Create a configuration.nix for machine-specific settings
Add the new machine to flake.nix under nixosConfigurations
Build with: sudo nixos-rebuild switch --flake .#new-machine

Updating the System

# Update flake inputs
nix flake update

# Rebuild system
sudo nixos-rebuild switch --flake .#my-machine

Customization Ideas

Add window manager configurations (i3, bspwm, Hyprland, etc.)
Configure terminal emulators (Alacritty, Kitty, WezTerm)
Set up status bars (Polybar, Waybar)
Add custom themes and color schemes
Configure rofi, dunst for notifications
Set up wallpaper management with nitrogen or variety
