Description

Enable NixOS users to install backlog.md through the NixOS package manager by creating Nix flake packaging

Acceptance Criteria

[x] Create flake.nix with proper derivation for building backlog.md
[x] Package builds successfully in NixOS environment using nix build
[x] CLI tool works correctly when run via nix run
[x] Documentation includes NixOS installation instructions
[x] Flake follows Nix community best practices

Implementation Plan

Research NixOS flake structure and best practices for Bun projects
Create flake.nix with proper inputs and derivation
Configure build process for Bun compilation
Set up proper install phase and meta information
Generate flake.lock via nix flake lock
Test package builds and functionality
Update documentation with NixOS installation instructions

Implementation Notes

Successfully implemented NixOS packaging support using Nix flakes. Created a complete flake.nix that:

Approach taken:

Used stdenv.mkDerivation with Bun and Node.js 20 as build inputs
Dynamically reads version from package.json using builtins.fromJSON
Follows Nix community best practices with proper meta information
Includes dev shell for development environment

Features implemented:

Complete Nix flake with nixpkgs and flake-utils inputs
Proper build process that runs CSS build and CLI compilation
Version embedding using --define flag during build
Development shell with all necessary dependencies
Package available via nix run and nix build

Technical decisions:

Used --frozen-lockfile for reproducible builds
Embedded version at build time using __EMBEDDED_VERSION__ define
Updated package.json version to 1.5.0 for proper versioning
Added NixOS installation command to README.md

Modified files:

flake.nix - Created complete Nix flake definition
flake.lock - Generated lockfile for reproducible builds
package.json - Updated version to 1.5.0
README.md - Added NixOS installation instructions
