docs(report-back): the standards lane reads the artifact from d253de27; the campaign is unblocked (#643)

## Why

This follows up
[#626](#626).
Its rollout docs still said the standards half was prepared but not on
`main`, and that every fixer run would exit 3. The standards half has
since merged as `d253de27`
([metadatastician/standards#1363](metadatastician/standards#1363)).

## What

- **`docs/REPORT-BACK.adoc` §5 step 3** now names standards `d253de27`
as the first commit whose Hypatia lane reads the `fleet-report-backs`
artifact. It also says callers on an older pin must bump it first.
- **`docs/REPORT-BACK.adoc` §6** says the campaign can run and records
the measurement below.
- **`ROADMAP.adoc`**: the rollout line now says the campaign is
unblocked.

## Evidence

I ran the merged fixer at `e44af814` against a scratch repository with
`STANDARDS_DIR` pointing at a standards checkout.

| Standards pin in the workflow | Fixer exit | What it reported |
|---|---:|---|
| `d253de27` (#1363 merged) | 0 | "wired end to end" |
| `9ae23875` (before #1363) | 3 | MANUAL: bump the standards pins |

## Not in this PR

- The pin bumps that move each consumer to `e44af814` are separate PRs:
  - metadatastician/standards `fork-governance.yml` `FLEET_REF`
- hyperpolymath/rsr-template-repo `fork-governance.yml` `FLEET_REF`,
plus the 85-minute job limit
  - hyperpolymath/metamanifold-webui's reusable pin
- This repository's own `hypatia-scan.yml` still pins standards at
`75bd5994`, which predates the input. Its fleet rows come from the
separate dogfood workflow. Moving that pin is the standards
pin-propagation PR's job.

+standards pin at `d253de27` and `FLEET_REF` at this repository's
+`e44af814` the fixer exits 0 ("wired end to end"); on the earlier pin
+`9ae23875` it exits 3 and names the bump. A repository whose standards pin
+predates `d253de27` therefore takes the pin bump and the fixer in the same
+branch.
