Update nixpkgs

Update the three nixpkgs flake inputs: nixpkgs-linux-stable, nixpkgs-darwin-stable, and nixpkgs-unstable.

Step 1: Confirm

Use AskUserQuestion to confirm before running. This modifies flake.lock.

• Question: "Update all three nixpkgs flake inputs (linux-stable, darwin-stable, unstable)?"
• Header: "Confirm update"
• Options:
  1. Yes, update all three (Recommended)
  2. No, cancel

If the user picks "No" or "Other" with anything other than clear consent, stop and report cancellation.

Step 2: Run

nix flake update nixpkgs-linux-stable nixpkgs-darwin-stable nixpkgs-unstable

Step 3: Report

Summarize what changed: which inputs moved, old → new revs if shown. Suggest a follow-up darwin-switch or nixos-rebuild only if the user asks.
