feat(cli): combined product picker with eval products + clipboard fix

- Interactive `msdl` (no flags) now lists consumer + eval products in one
  picker with an Evaluation / Enterprise separator; selecting a server
  product routes to the eval flow automatically
- copyToClipboard calls clip.exe by full SystemRoot path, bypassing
  cmd.exe PATH lookup that failed in some terminal environments
- CliHandoff card: winget primary install + msdl (no .exe) in run command
