Write a provisioner client's files only on a change over the bus, never on a timer (issue 1129, ADR 0349 clause 4)

WithdrawRecord only ended the waiting ask locally; the router kept it open, so
the operator still saw Approve/Decline for a withdrawn record and an answer to
it was dropped silently. It now also publishes a cancel on the router's
subject once the withdraw is saved, as the controller's asker does; a cancel
the router cannot be told of is logged and the withdraw still stands. The
module's existing "uses": ["operator-channel"] already grants this; no manifest
change needed, since the ask and cancel subjects are both under that seat.

+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.

+// "Config" replaces "settings": a manifest declares its values under `config`, a mergeable file names the keys it
+// takes under `takes-config`, and a file asks for a value with `${config:<key>}`. A mergeable file naming no keys at
+// all is the settings form's last shape: it takes every key of its module's layer and declares none, so mesh-config

+// moved, and are then refused (ADR 0348 §1). The modules not yet moved are listed in the file `unmoved` beside this
+// check, one per line: the catalogue's list ADR 0348 §11 names. Every other module says no old name, in its

+// line the trunk's copy (the merge base's, given with -base) does not hold is refused, so the list only shrinks;

-# build-agent
-
-The mesh's build machine as a role every machine can hold (novox/hq ADR 0190). It holds the node seat
-`node-build-agent`: every holder pulls one build at a time from the role's one work queue when it is
-idle, so a tier of many images is built by as many machines as hold the seat and are online, and a
-machine that is off builds nothing and blocks nothing. The controller asks the role, never a machine;
-the outcome names the machine that built it.
-
-What a holding machine needs is what the builder always needed, said here once: a container runtime
-(the socket is mounted), the artifact store as a provision, a workspace, and the bus credential. The code is `cmd/mesh-builder` in the mesh-controller repository, compiled from
-that repository's main (`build.artifacts[].context`); this module ships the packaging.
-
-Assign it to every machine with a container runtime. It replaces `builder`, the one-holder form of the
-same thing; retire that once this is assigned where it was.
-
-A send that replaces the agent's container does not throw away the build it runs: the container declares
-`busy` as `/usr/local/bin/mesh-builder busy` (novox/hq ADR 0335). The node-engine asks it before replacing it; from that
-ask the agent takes no new build, the node-engine leaves it running while it says a build is in hand, and
-replaces it once it says idle, or after 15 minutes at the latest.
-
-## The package registry (novox/hq ADR 0336)
-
-The package registry (`npm-package-registry`, provided by the gitea module) is an optional requirement.
-Genesis assigns the build agent before anything provides it, so the agent is assignable on a mesh with no
-registry, and `mesh-controller.plan` and `node` list the requirement as unbound until the gitea module is
-assigned; it then binds with no further act.
-
-Until it binds, the agent on genesis's node reads the `genesis-package-registry` own-secret, which the
-installer seals to it at the packages step: the forge it raised, the port, the npm path, the account
-`mesh-builder` and its password. Issued outside the mesh, so no other machine is given one. A real binding
-wins over it, and each build's log says which the build resolved from. A build that needs the registry (a
-`package` artifact, an image whose Dockerfile names `.npmrc`, a TypeScript artifact with an `@novox/`
-dependency) on an agent with neither fails before building, naming the machine. Go artifacts and images
-that do not name `.npmrc` build without it. `manifest_test.go` holds the manifest to this.
