A project planner: dependency validation, scaffold commands, and a build-pipeline simulator.

Checkpoint: the project planner

Task: implement in Solution:

  1. static bool HasCycle(List<(string Project, string DependsOn)> refs) — true when the dependency graph contains a cycle (A→B→A).
  2. static string ScaffoldCommand(string kind, string name) — "console" → dotnet new console -o {name}; "classlib" → dotnet new classlib -o {name}; unknown kind → ArgumentException.
  3. static List<string> FailingProjects(List<(string Project, string DependsOn)> refs, List<string> broken) — projects that are broken or transitively depend on a broken one (alphabetical order).
