refactor: organize hosts configs into dedicated directory

- Move and rename host-specific configurations (e.g., wsl to hosts/wsl)
- Add home.nix files for mbp and wsl, importing common modules
- Update mbp flake.nix path to new hosts/mbp/configuration.nix
- Integrate home-manager for user environments on macOS/WSL
- Update flake.lock inputs (nixpkgs, home-manager, homebrew) for latest versions
- Add README.md with project overview and setup instructions

This restructures the repo for multi-host support, improves modularity, and ensures reproducible builds with updated dependencies.
