The checked-in fixtures/ apps (Rails 2 to 6, Rails 5 API, Sinatra and Padrino 0.10.7) and test/integration no longer install, and CI doesn't run them.

Change

• A new apps job in .github/workflows/ci.yml for Rails 7.2 (Ruby 3.1), Rails 8.1 (Ruby 3.4) and Sinatra (Ruby 3.4). Its actions are pinned to the same SHAs as release.yml, and it runs with contents: read.

• test/apps/build_and_test.sh generates the app (rails new --minimal, or an empty Sinatra app), copies in test/apps/shared plus the app's own files, adds rabl from the checkout with path:, and runs the app's tests.

• Ported behaviours:

  • collections with extends, custom attribute names, child (and nested), glue, conditional child and node, object =>, partials with and without locals, app and Rails view helpers;
  • escape_all_output, Rabl.render with a view-context scope;
  • HTML views and a layout rendering rabl;
  • a custom MIME type, XML, an ActionController::API controller;
  • caching, including cache_all_output.

  Sinatra gets everything except HTML, MIME, XML and API.

• Removed:

  • fixtures/ and test/integration/;
  • test/silence.rb;
  • the Rakefile test:clean, test:setup, test:fixtures and test:full tasks;
  • rack-test from the Gemfile.

  The gem's file list is unchanged, and rake test still runs test/*_test.rb.

• Dropped deliberately:

  • The Rails 2–6.0 and Padrino 0.10.7 apps: unsupported versions that don't install. A generated Padrino app could follow.
  • The hard-coded md5 cache-key assertions: they were stale, and they only detected changes. A behaviour check replaces them: rows are updated, and the cached response must still be served.
  • The exact time-format assertions: times are compared to the second.

Verification

• Locally, generated fresh from the committed tree:
  • Rails 8.1.4: 12 runs, 0 failures; also with seeds 1–3 and with frozen string literals.
  • Rails 7.2.4 on Ruby 3.1: 12 runs, 0 failures.
  • Sinatra 4.2.1: 8 runs, 0 failures.
• The tests bite: with rabl's lib mutated (caching off, cache_all_output off, the railtie's API-rendering include removed, the source format forced to JSON, escaping removed), the matching app tests fail. Unmutated, all pass.
• Unit suite: lib is unchanged, and it still passes 541/0.

Not verified

• The job on GitHub Actions itself; this PR's run is the first.
• Ruby 3.4 locally (CI uses it; I ran 3.3).

Conflicts with the ActiveSupport-floor PR in Gemfile only.
