Fix VS Code extension CLI invocation failures on PowerShell and paths with spaces

[Copilot]

WinApp CLI commands routed through the VS Code extension fail in PowerShell terminals due to missing & call operator, and the debug adapter's spawn call breaks when the extension path contains spaces.

Changes

• Terminal commands — PowerShell & operator (runWinappCommand): PowerShell treats a bare quoted string as an expression, not an invocation. Prefix with & so it executes:

  // Before
  "C:\path\to\winapp.exe" get-winapp-path --global   // ParserError in PowerShell
  
  // After
  & "C:\path\to\winapp.exe" get-winapp-path --global  // works in PowerShell and cmd.exe
  

• Debug adapter — replace shell string with args array (WinAppDebugAdapterFactory): The adapter was joining all args into a single string and spawning with shell: true, which silently breaks when winapp.exe lives under a path with spaces (e.g. C:\Users\John Smith\...). Switch to spawn(cliPath, spawnArgs, { shell: false }) so the OS receives the executable path and arguments directly, with no shell parsing involved:

  // Before
  const command = [cliPath, 'run', `"${inputFolder}"`, '--manifest', `"${manifest}"`, '--json'].join(' ');
  spawn(command, { shell: true });
  
  // After
  const spawnArgs = ['run', inputFolder, '--manifest', manifest, '--json'];
  spawn(cliPath, spawnArgs, { shell: false });

Description

Fixes WinApp CLI commands failing when invoked through the VS Code extension. The debug adapter (WinAppDebugAdapterFactory) was constructing a shell command string joined with spaces and spawning with shell: true, which breaks when winapp.exe lives under a path containing spaces. The terminal command helper was also missing the PowerShell & call operator.

Usage Example

# Before - ParserError in PowerShell:
"c:\Users\user\.vscode\extensions\winapp-0.2.0\bin\win-arm64\winapp.exe" get-winapp-path --global

# After - works correctly:
& "c:\Users\user\.vscode\extensions\winapp-0.2.0\bin\win-arm64\winapp.exe" get-winapp-path --global

Additional Notes

Two fixes in src/winapp-VSC/src/extension.ts:

1. runWinappCommand: Added & call operator so PowerShell executes the quoted path as a command.
2. WinAppDebugAdapterFactory: Changed spawn(command, { shell: true }) → spawn(cliPath, spawnArgs, { shell: false }).
