Craft Mishuk — Sync Missing API Route Commands

Craft Mishuk highlighted assistant attribution: prepared by Craft Mishuk under Master Mishuk Adhikari's request to add the missing commands from the API branch into the standalone xCloud CLI.

Summary

• Adds missing Public API typed commands for Cloudflare integrations, sudo-user create/delete, WordPress site creation, site monitoring, and SSH update.
• Adds Enterprise API site-management typed commands from the API docs: list/show/create/update/delete, suspend, staging/publish, cache purge, and SSH key management.
• Adds multi-parameter route path resolution so commands like sudo-user deletion can map both server and sudo-user UUIDs.
• Allows raw xcloud api put ... for PUT endpoints.
• Updates README command examples and adds route coverage tests.

Verification

• git diff --check
• node --check bin/xcloud.js
• node --check lib/*.js test/*.js
• npm test
• npm pack --dry-run
• npm install -g . --prefix /tmp/xcloud-cli-global-api-sync
• /tmp/xcloud-cli-global-api-sync/bin/xcloud --help
• Verified destructive guard returns structured ConfirmationRequired JSON for servers delete-sudo-user without --yes.
