## Approach
This repo is the source of truth for the machine's reproducible developer
environment:
environment across macOS and Linux:
- `home/` contains the Home Manager modules for user-facing tools
- `config/` contains the repo-owned config trees copied from your daily setup

that are still easier to keep in Brew on macOS
- `home/migration.nix` contains one-time ownership handoff logic from `~/dots`
into Home Manager so the steady-state modules can stay focused on real config
- `lib/package-sets.nix` defines the shared CLI package subsets used by both
macOS and Linux hosts
## Layout
- `flake.nix`: top-level flake and host wiring
- `hosts/hari-macbook-pro/default.nix`: this machine's host config
- `hosts/workstation/default.nix`: standalone Linux Home Manager host config
- `modules/base.nix`: Nix settings and core packages
- `modules/macos.nix`: macOS defaults and host-level settings
- `modules/packages.nix`: system packages and fonts
- `modules/homebrew.nix`: the remaining Homebrew-managed GUI apps
- `home/`: Home Manager modules for shell, editor, CLI tools, and app config
- `home/common.nix`: shared Home Manager imports used by macOS and Linux
- `home/linux.nix`: Linux Home Manager entrypoint
- `home/migration.nix`: transitional cleanup for old `~/dots` symlinks
- `config/`: repo-owned config files consumed by Home Manager

First switch:
```bash
nix run github:LnL7/nix-darwin/master#darwin-rebuild -- switch --flake .#hari-macbook-pro
nix run github:LnL7/nix-darwin/master#darwin-rebuild -- switch --flake path:.#hari-macbook-pro

First Linux switch:
```bash
