Add a Nix flake that builds the CLI from source using buildNpmPackage with Node.js 22, exposing `claude-flow` and `ruflo` binaries. Fix EACCES errors during `init` when the package lives on a read-only filesystem (e.g. Nix store): copyFileSync preserves source permissions, so copied helper/command files were read-only and subsequent overwrites failed. Now every copyFileSync is followed by a chmodSync to ensure the destination is owner-writable. Co-Authored-By: claude-flow <ruv@ruv.net>

On NixOS (and any Nix-based setup), packages installed via Nix live on a read-only filesystem. This causes two problems:
flake.nixto build the project from source with Nix tooling.initcommand crashes —copyFileSynccopies files with source permissions intact; files from the Nix store are read-only, so any later write to those copies throwsEACCES.Test plan
