// Simple dev helper CLI implemented as a .NET file-based app using Cocona.
// Usage examples (run from repo root):
//   ./dev.cs --help
//   ./dev.cs cleanslate
//   ./dev.cs cleanslate Sentry-CI-Build-macOS.slnf
//   ./dev.cs subup
//   ./dev.cs wrest
//   ./dev.cs nrest
//   ./dev.cs aiup
//   ./dev.cs cleanslate --dry-run
//
// This is intended to be run from the repo root so that git/dotnet
// commands operate on this repository.
