fix(rsr-verify): accept .adoc — the docs exist, the check named .md (#194)

`rsr-verify.sh` fails 7 documentation checks in a plugin whose
documentation **is complete**.

```
checks for:   docs/ARCHITECTURE.md  docs/API_REFERENCE.md  docs/FAQ.md
              docs/QUICKSTART.md    docs/TROUBLESHOOTING.md
              docs/EXAMPLES.md      docs/MIGRATION.md

on disk:      docs/ARCHITECTURE.adoc  docs/API_REFERENCE.adoc  docs/FAQ.adoc
              docs/QUICKSTART.adoc    docs/TROUBLESHOOTING.adoc
              docs/EXAMPLES.adoc      docs/MIGRATION.adoc
              (plus CITATIONS.adoc and COMPATIBILITY.adoc)
```

Every document exists. The `.md` → `.adoc` migration moved them and left
the verifier naming the old extension, so **7 of the RSR compliance
checks have been failing on a compliant plugin**.

## Fix

Accept either extension — the same pattern the RSR template's own
`quality.yml` already uses for README, LICENSE and CONTRIBUTING:

```bash
check "ARCHITECTURE exists" "[[ -f docs/ARCHITECTURE.md ]] || [[ -f docs/ARCHITECTURE.adoc ]]"
```

The check label drops the extension too, so a failure message names the
*document* rather than a filename that may be either form.

## Verified

| | |
|---|---|
| checks satisfied against files actually on disk | **7 / 7** |
| still missing | **0** |
| `shellcheck -S error` | **0 findings** |

## Provenance

Found by an estate-wide sweep of 5,111 scripts across 375 repos. Same
defect class as the 56 unsatisfiable checks repointed across 18 repos
earlier in this campaign (see hyperpolymath/Axiom.jl#82).

⚠ I initially filed these as *missing documentation* in
hyperpolymath/standards#653 and was about to author 14 replacement
files. That was wrong — my classifier looked for the `.adoc` twin at the
**repo root**, but these live at `asdf-ghjk/docs/`, so it reported no
twin. Issue #653 is being corrected.
