feat(ip-pool): add guest-side static-IP boot scripts

template/guest-setup/linux/ci-report-ip.sh
  Updated version: checks guestinfo.ip-assignment first (static path),
  falls back to DHCP detection if absent.  Applies static IP before
  network-online.target so SSH starts on the correct address immediately.

template/guest-setup/linux/ci-report-ip.service
  Drops 'network.target' from After= — runs before network is up so the
  static IP is configured before SSH/other services start.

template/guest-setup/windows/ci-static-ip.ps1
  Reads guestinfo.ip-assignment via vmware-rpctool at system startup (SYSTEM
  account Task Scheduler task).  Disables DHCP, applies static IP+gateway,
  reports back via guestinfo.ci-ip.  No-op when ip-assignment is absent.

template/Install-CIToolchain-Linux2404.sh
  Step 7b now copies scripts from guest-setup/linux/ instead of embedding
  the old DHCP-only inline script.
