jakman85andClaude Opus 4.8 5d2b248b68 Phase 1 toolchain: pinned dev container (prereqs not all Python)
Per operator rule: OpenTofu/age/sops/flux are Go binaries, so bake the toolchain
into a pinned Fedora-44 dev container (matches host libvirt 12) instead of a venv.
infra/devcontainer/: Containerfile + versions.env (tofu 1.9.0, age 1.2.1, sops
3.9.4, flux 2.4.0, kubectl 1.32.0, helm 3.16.0) + dev.sh (runs with host libvirt
socket + repo + ssh mounted) + README. Built & validated: all tools resolve;
virsh reaches host libvirt from inside the container.

Also record resolved Phase 1 decisions in PHASE1-SCOPE.md (6GiB/4vCPU x3;
k3s-dev NAT 10.73.0.0/24; container toolchain). Gate green.
