Judge an upstream pin's host like any name, and harden the upstream unpack (review 35, hq issue 345)

The url was skipped by the installation check, so an installation's host or
an address passed; it is judged whole now, the vendor's host declared in the
artifact's names-on-purpose, and an address or a reserved name as the host
is refused. Only the version's dotted-quad reading is skipped. The unpack
caps its entries, drains xz before waiting for it, reads a pax global
header and a nested within's parents, and a redirect off https is not
followed.

-// plan's, a release's, a healer's, a rotation's, and the bus step too, which is a person's act but composes under
-// sendKeeps like the rest. On 2026-10-02 two merges a minute apart made two plans;
-// the controller's plan rolled the new controller, which widened its seat's row, and the node-engine's plan then
-// sent the control node the controller build before it. The older binary read the row it could not serve and the
-// mesh lost its voice for ten minutes — the thing that would have corrected it was the thing that was down. ADR
-// 0185 took the outage out of it (a controller behind its row serves what it can); the race is closed here,
-// without needing its trigger: whatever made the mesh's record older, the send keeps the build.
-//
-// **Kept, not refused.** The send composes the controller or the node-engine at the build the machine was last
-// sent, as a recorded module is kept (ADR 0245), and carries everything else: no other module, secret, healer or
-// walk waits on it, and nothing is retried. The kept move is no move for a gate either: ungatedIn and gatedSend
-// leave it out (withoutKept), so a gate judges the other moves of its send. A plan whose own build is the older one finds its gate superseded by
-// the build kept there (issue 352) and ends. The mesh's record stays older, and a warning condition says so until
-// a send carries the record — a person's `push <node>` accepts the older build — or the record moves forward: a
-// newer merge, or `rebuild mesh-controller`.
-//
-// Older is by the builds' registration order — when each was asked (novox/hq issue 219) — never by the commits'
-// dates. So a retry or a rebuild of an old commit, asked anew, counts as newer: it is registered as the module's
-// current build by the same order, and the guard does not stop that move. A build that failed its gate is never
-// ahead: the machine was sent it and the record was put back before it (gateFailed), and if the put-back's own
-// send was refused, the next send completes it rather than keeping the failed build there. A gate's own put-back
