Pin the image's Go base in the Dockerfile, which genesis builds as it stands (hq issue 223)

Genesis now raises a process-form controller as a container built from
this repository's Dockerfile with no build arguments (mesh-host
bootstrap, novox/hq issue 223); the manifest builds no image, so nothing
passes the base in. The default was a tag older than go.mod asks for.
It is now the digest the Makefile pins, and a test holds the two equal.

 ## The image
 
+**The mesh no longer runs the controller from it** (novox/hq issue 213). The module declares a Go
+bundle, `controller`, which the host on the controller's machine unpacks and runs as the process
+`mesh-controller` under the account of the same name (ADR 0188 §1, §3). The image stays for what
+still runs a container of the controller: genesis, which raises the first controller from it and
+installs the module from its manifest (mesh-host `internal/bootstrap`), and the lab. Neither is the
+mesh's own build any more — `make image` builds it.
+
 `FROM scratch`, holding one statically linked binary and nothing else — no shell, no package
 manager, no libc, no CA certificates.

+// the toolchain image's node_modules. Nothing ever put anything in the first, so a module needing a
+// database driver (`pg`, `mongodb`, `mssql`) could not be a bundle at all, and kept a container whose
+// recipe installed it by hand (novox/hq ADR 0198 §4: "the backend's own driver inside the bundle").
+// Now the module's `package.json` says what it depends on, as any Node package does, and the build
+// installs exactly that into the module's own directory before compiling.
+//
+// **The SDK the toolchain carries is the one a bundle is built with, whatever the module says**
+// (novox/hq issue 212: the toolchain is rebuilt on every SDK release and every bundle after it). A
+// module's `package.json` names `@novox/mesh-sdk` with a range — it has to, to type-check on a
+// workstation — and installing that range would shadow the toolchain's copy for this module alone:
+// one module compiled against an older SDK than its neighbours, chosen by a caret nobody re-reads.
+// So the SDK is taken out of what is installed (and never fetched), and any copy something else
+// pulls in is removed afterwards; every import of it resolves past the module's node_modules to the
+// toolchain's. A module therefore cannot pin a different SDK, by design: the toolchain is the pin.
+//
+// **Correctness before speed.** Every build installs afresh into a fresh clone, from the lockfile
+// when the module has one (`npm ci`, exact) and from its ranges otherwise; nothing installed is kept
+// between builds. What is shared is npm's own download cache, a named volume, which is
+// content-addressed and verified by integrity on every read — it saves the network, never the
