Pin the feature's SDK and node-engine so the release controller builds mesh-host's new code (issue 804)

mesh-host's declaration code now imports mesh-sdk's seal package (issue 755);
the release branch's controller vendors mesh-host, so it needs both pins
before mesh-host's own pull request can be judged by it.

+# Release 57: config and provisioning
+
+This branch carries the work of hq design 57 (ADR 0348, ADR 0349) in this repository. Each package
+merges here through its own reviewed pull request; the branch reaches main as one pull request, in one
+delivery group with the branch of the same name in mesh-controller, mesh-host, mesh-sdk, mesh-catalog
+and hq, after a rehearsal in the lab. This file is deleted by the last commit before that pull request.
