CLI site creation fails when generating default admin password

[chubes4]

Summary

studio site create --no-start can fail in the Node-based CLI when Studio generates the default WordPress admin password.

The shared password helper currently imports generatePassword from @automattic/generate-password. That package calls window.crypto.getRandomValues(...), which is valid in browser-like runtimes but not in the Node CLI, where window is undefined.

Impact

A new site can reach the port-assignment step and then fail before saving the site:

✔ Port assigned: 9457
✖ Failed to create site: window is not defined

This also blocks reliable local Homeboy evidence runs for other Studio CLI/site-startup investigations because fresh site creation fails before the benchmark can proceed.

Root cause

Current trunk code path:

studio site create
→ apps/cli/commands/site/create.ts
→ createPassword()
→ tools/common/lib/passwords.ts
→ @automattic/generate-password
→ window.crypto.getRandomValues(...)
→ ReferenceError: window is not defined

The password is the default WordPress admin password generated when the caller does not provide one.

Observed trace excerpt:

✔ Port assigned: 9457
✔ Site created successfully
exit_code: 0
success: true

Expected behavior

The CLI should be able to generate a default WordPress admin password without requiring a browser window global.

Notes

A runtime-neutral implementation can use globalThis.crypto.getRandomValues(...), which is available in the Node CLI runtime and browser-like runtimes.
