fix(rsr-audit): credit estate-correct format/case choices (58% -> 86% Bronze)

rsr-audit.sh failed repos on deliberate, policy-correct choices rather than
real gaps. De-brittled the two core helpers + the CI check (format/case ONLY
-- licence *content* checks untouched, owner-gated):
- check_file_exists / check_file_contains also credit .adoc docs (estate docs
  policy mandates AsciiDoc), `Justfile` case, and bare `LICENSE`.
- CI check accepts GitHub Actions (.github/workflows/*.y*ml) as first-class,
  not just GitLab CI / a hardcoded ci.yml. The estate runs on GitHub; the RSR
  satellite CLAUDE.md itself notes the old GitLab guidance is superseded.

NOT changed (flagged for owner): the LICENSE.txt "MIT AND Palimpsest" *content*
checks contradict the estate's MPL-2.0-for-sole-owner policy -- updating what
licence the standard mandates is an owner decision.

Effect: standards self-audit 58.46% -> 85.92% (BRONZE). Helps all 10 repos.
