feat(linux): add Ubuntu 24.04 template VM automation scripts
Deploy-LinuxBuild2404.ps1 (host-side):
- Downloads Ubuntu 24.04 cloud VMDK (cached in F:\CI\ISO\)
- Generates cloud-init seed ISO (nocloud + guestinfo backup datasource)
- user-data: user+SSH key only no packages/runcmd, all provisioning
delegated to Prepare/Setup (removed -MinimalConfig, now always minimal)
- Assembles VMX, powers on VM, waits for cloud-init completion via SSH
- Removes seed ISO from VMX after first boot (ide1:0 disabled)
- Next-steps message uses correct -VMIPAddress parameter
Prepare-LinuxBuild2404.ps1 (host-side):
- Powers on template VM, waits for SSH readiness
- Copies Setup-LinuxBuild2404.sh into guest, runs it with sudo
- Validates setup result (all tools in PATH, dirs, sshd, swap off)
- Takes snapshot BaseClean-Linux (cold, VM shut down before snapshot)
- -NoMingw switch to skip mingw-w64 cross-compiler installation
Setup-LinuxBuild2404.sh (guest-side):
- apt update/upgrade, build-essential, gcc, g++, clang, cmake, ninja
- python3, pip3, venv; git, p7zip-full, curl, wget, ca-certificates
- Optional .NET SDK (--dotnet), mingw-w64 cross-compiler (--no-mingw to skip)
- /opt/ci/{build,output,scripts,cache} dirs (ci_build ownership)
- SSH hardening (PasswordAuthentication no, PubkeyAuthentication yes)
- Swap disable (swapoff -a + fstab), MAC-agnostic netplan for linked clones
- ci-report-ip systemd service (guestinfo.ci-ip reporter)
- apt auto-update disabled; full validation gate at end
