bootstrap: the temporary control plane gets a temporary name

Browse Source 
The substrate raises a control plane and a module will later declare one. If both
are called `mesh-control` then for one moment two owners hold one container, and
the host — which tracks what it owns — has no way to stop owning something without
destroying it. That looked like a missing mechanism.

It is a naming problem. The substrate's container becomes `temp-mesh-control` and
the module's keeps the plain name: two containers, two owners, nothing to hand
over. Dropping the temporary one from the bundle at the end is then destruction by
omission, which is what the host already does to anything that leaves a
declaration — and the right end for something named "temp" (novox/hq ADR 0067).

The rename is textual and matches the QUOTED name, so the `mesh-control` inside
the image reference is not caught by it. Read back afterwards: the produced bundle
must call it the temporary name, and no other container may have been renamed.
