ops(kind): skip Substrate's observability stack by default (930 MiB of 2.3 GB); opt in with OUSAST_KIND_OBSERVABILITY=1

A lean overlay omits otel-collector, prometheus and jaeger and disables the exporters; on an existing cluster up.sh scales them to 0. Verified live: render has no otel-system resources, up.sh idempotent (54 s second run), smoke Run done, kind node 2.66 -> 1.82 GiB. Docs say server VM. Implemented with Codex.

+Usage: python ops/ax/prepare-substrate.py SOURCE EMPTY_DESTINATION
+The destination lives only for an install/render. Source/build inputs are symlinked;
