Minimal harness for kind: customer_script nodes (agent-runtimes
spec/tenant-namespaces.md SCR-1..SCR-6). No LLM turn - runs via the
"shell" runner, agent-repo/v1 clone access only. Per-script credential
needs are deliberately not baked into this base (SCR-6: narrow,
per-script review) - compose a customer-script-<need>/v1 variant
layering whichever specific credential context a given script actually
needs, rather than widening this shared base.
Without this commit, kind: customer_script was not dispatchable from
any machine other than the one it was authored on - the harness lookup
against a fresh CRS sync would fail.
