📄 Description

Summary

This PR adds Nix flake support to OpenTUI, enabling declarative, reproducible installation across different systems and architectures through the Nix package manager.

Motivation

Currently, OpenTUI installation requires running a bash script that downloads and installs binaries system-wide. While this works well for traditional setups, it presents challenges for:

Declarative system management: NixOS and nix-darwin users prefer declarative package management where system state is defined in configuration files
Reproducible environments: Development teams need consistent, reproducible dev environments across different machines
Isolated development: Developers want to try OpenTUI without system-wide installation
CI/CD pipelines: Nix provides excellent caching and reproducibility for CI environments

What This PR Adds

1. `flake.nix` - Main flake definition

Multi-platform support (x86_64 and aarch64 for Linux and macOS)
Automatic platform detection and correct binary selection
Proper library naming (.so vs .dylib) based on OS
pkg-config file generation for build system integration

2. `flake.lock` - Pinned dependencies

Ensures reproducible builds across all systems
Uses nixpkgs unstable for latest packages

3. Updated README

Clear installation instructions for Nix users
Examples for different use cases (dev shell, system package, flake input)

Benefits

Zero system pollution: Users can try OpenTUI in an isolated shell without installing anything globally
Declarative configuration: NixOS/nix-darwin users can add OpenTUI to their system configuration
Development shells: Teams can share consistent dev environments with all required tools
Better CI integration: GitHub Actions and other CI systems can leverage Nix caching
Version pinning: Flake.lock ensures everyone uses the same version until explicitly updated

Usage Examples

# Quick try without installation
nix develop github:sst/opentui

# Add to dev environment
nix flake init -t github:sst/opentui

# System-wide on NixOS
environment.systemPackages = [ opentui.packages.${system}.default ];

Notes

The flake downloads pre-built binaries from GitHub releases, matching the existing install.sh behavior
No changes to existing installation methods - this is purely additive
Follows Nix best practices for packaging external binaries
Includes development shell with common tools (Go, Bun, Zig)

This enhancement makes OpenTUI more accessible to the growing Nix community while maintaining full compatibility with existing installation methods.
