Simone 1bc3ec601c 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.

# CI VM IP reporter — called by ci-report-ip.service at boot.
#
# Phase C extension: reads guestinfo.ip-assignment from the VMX (written by the
# host orchestrator before vmrun start). If present, applies a static IP to
# the primary NIC and reports it back immediately via guestinfo.ci-ip, skipping
# DHCP entirely. If absent, falls back to the original DHCP-detect behaviour.
#
# The VMCI channel (vmware-rpctool) does not require TCP/IP to be initialised —
# it communicates via the VMware virtual hardware interface. This means the
# static IP can be configured before network-online.target, so by the time SSH
# starts listening the NIC already has the correct address.
