.SYNOPSIS
  Provision a Windows VM (or bare machine) with everything needed to build and
  test clide's windows-support branch, then run the ConPTY soak.

.DESCRIPTION
  Installs (via winget): Git, the Flutter SDK (brings Dart), and Visual Studio
  2022 Build Tools with the C++ desktop workload — required for both the
  ConPTY FFI path and the `clide.c` AF_UNIX CLI (ws2_32 / afunix). Then clones
  the repo, checks out the branch, runs `flutter pub get`, and builds the C
  client. Nothing here freezes the box; it just gets you to a runnable state.

  Run from an ELEVATED PowerShell (winget package installs need admin). After
  it finishes, open a NEW shell so PATH updates take effect, then run
  soak-conpty.ps1.

.PARAMETER RepoUrl   Git remote (default: the GitHub origin).
.PARAMETER Branch    Branch to check out (default: windows-support).
.PARAMETER Dest      Checkout directory (default: %USERPROFILE%\src\clide).
