Windows install is missing `gws.exe`, causing `gws auth setup` to fail with ENOENT

[Hanekawa-00]

Environment

• OS: Windows
• Node.js: compatible with the package requirement (>=18)
• npm: global install

What I ran

npm uninstall -g @googleworkspace/cli
npm cache clean --force
npm install -g @googleworkspace/cli
gws auth setup

What happened
The command fails with:

Error: spawnSync C:\Users\Hanekawa\AppData\Roaming\npm\node_modules\@googleworkspace\cli\node_modules\.bin_real\gws.exe ENOENT
    at Object.spawnSync (node:internal/child_process:1119:20)
    at spawnSync (node:child_process:911:24)
    at C:\Users\Hanekawa\AppData\Roaming\npm\node_modules\@googleworkspace\cli\binary-install.js:197:24
    at process.processTicksAndRejections (node:internal/process/task_queues:104:5) {
  errno: -4058,
  code: 'ENOENT',
  syscall: 'spawnSync C:\\Users\\Hanekawa\\AppData\\Roaming\\npm\\node_modules\\@googleworkspace\\cli\\node_modules\\.bin_real\\gws.exe',
  path: 'C:\\Users\\Hanekawa\\AppData\\Roaming\\npm\\node_modules\\@googleworkspace\\cli\\node_modules\\.bin_real\\gws.exe',
  spawnargs: [ 'auth', 'setup' ]
}

Verification
I checked whether the expected binary exists:

Test-Path "C:\Users\Hanekawa\AppData\Roaming\npm\node_modules\@googleworkspace\cli\node_modules\.bin_real\gws.exe"

Result:

False

So the package appears to install successfully via npm, but the actual Windows binary is missing from the location the wrapper expects.

Expected behavior
npm install -g @googleworkspace/cli should install or place gws.exe in the expected path so gws auth setup can run.

Notes
This looks like a packaging/install-script issue specific to Windows, rather than a Node version issue.
