Remove [KSOLO-DBG] per-step echos from init.sh. The /dev/console redirect
stays — it's load-bearing for early-boot visibility on QEMU virt.
Add docs/arm64-status.md capturing the end-of-Phase-3 state:
- What works (full boot through 14 stages, KubeSolo + containerd start)
- Known limitations of the dev setup (QEMU TCG perf, /dev/vda4 hardcode,
busybox-static gaps)
- What's needed to ship v0.3 ARM64 as production-ready
Real-hardware validation (Graviton, Ampere, or similar) is the next gating
step before we can call ARM64 generic done.
