Add classic Unix social tools and fortune on login

- bsd-finger, ytalk, fortune in systemPackages
- Fortune displays on interactive shell login via programs.bash.interactiveShellInit
- Avoids breaking nix copy/rsync/scp (loginShellInit was wrong approach)

Works today.\n\n**Devshells work too:**\n```bash\n# In project with flake.nix\nnix develop\n```\n\n## Options\n\n| Option | Pros | Cons |\n|--------|------|------|\n| **Self-service only** | Minimal config, user learns nix | Cold start friction |\n| **Global defaults** | Zero friction for common tools | Bloats system, version conflicts |\n| **Starter script** | One command setup, customizable | Another thing to maintain |\n| **direnv + devshells** | Per-project envs, reproducible | Needs direnv installed globally |\n\n## Current State\n- `nix profile install` works for users ✅\n- `nix develop` works ✅\n- direnv NOT installed globally\n- Only python3, uv in system packages\n\n## Recommendation\n1. Add `direnv` to global packages (enables per-project devshells)\n2. Document `nix profile install` for quick one-offs\n3. Provide example flake.nix templates for Go, Node, Rust projects\n4. Keep system packages minimal (python3, uv, direnv, git, vim)\n\n## Test Results\n```\n$ nix profile install nixpkgs#go\n$ go version\ngo version go1.22.8 linux/amd64\n```","status":"closed","priority":2,"issue_type":"task","created_at":"2026-01-02T12:27:32.894163417-08:00","created_by":"dan","updated_at":"2026-01-02T12:32:32.502649201-08:00","closed_at":"2026-01-02T12:32:32.502649201-08:00","close_reason":"Users can self-install via nix profile.
