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.

 # --- Step 7b: CI IP reporter via VMware guestinfo ---
-# The host reads the guest IP via `vmrun readVariable guestVar ci-ip`.
-# IMPORTANT: vmware-rpctool sets 'guestinfo.ci-ip' but vmrun reads it as just
-# 'ci-ip' under the guestVar namespace (the 'guestinfo.' prefix is implicit).
-# This is the official VMware VMCI channel — works even when TCP/IP is not yet
-# fully initialised on the host. Used as primary; getGuestIPAddress is fallback.
+# Supports two modes:
+#   Static (ip_pool):  reads guestinfo.ip-assignment injected by the host
+#                      orchestrator, applies static NIC config, reports back.
+#   DHCP fallback:     waits for DHCP address, reports via guestinfo.ci-ip.
+# The script and service are sourced from template/guest-setup/linux/.
