Minitest 6.1.0 treats bare hashes passed to must_equal as keyword arguments, causing 13 existing behavior tests to fail before comparing the expected value. Give those expected hashes explicit braces so the same assertions work with minitest 5 and 6. Library code and dependency requirements are unchanged.

Ruby 3.1 also needs Ubuntu 24.04: the first CI run failed during Ruby setup after ubuntu-latest moved to 26.04. Use 24.04 for the supported Ruby matrix on x64 and arm64. This runner configuration is validated by CI rather than a source-text test.

The expanded matrix also exposed an existing order-dependent warning assertion: MultiJson deprecations can appear alongside the SDK's rate-limit warning when this test runs first. Require the exact warning line exactly once among stderr lines. Seed 13766 reproduces the failure before this assertion change and passes afterward.

Validation:

• Before the hash fix: Ruby 4.0.7 / minitest 6.1.0 reports 13 failures in existing SDK behavior tests.
• Ruby 3.1.0 (the gemspec minimum): 140 tests / 354 assertions pass with both the currently resolved minitest 5 and, separately, minitest 5.15.0 bundled with Ruby 3.1, using seed 13766.
• Ruby 4.0.7 / minitest 6.1.0 with Node signature parity and coverage enabled: 140 tests / 364 assertions pass with seed 13766; only the optional live upload is skipped locally.
• Native arm64 Ruby 4.0.9 / minitest 6.1.0: 140 tests / 354 assertions pass with seed 13766.
• bundle exec standardrb passes on Ruby 3.1 and 4.0 (x64), and Ruby 4.0 (arm64). git diff --check and actionlint pass.
• Final CI: all ten Ruby 3.1–4.0 jobs on x64 and arm64, plus the live upload integration test, pass.

Council review: six rounds. Rounds 1–3 were clean; round 4 requested retaining duplicate-warning detection, so the warning assertion now counts exactly one matching line. Rounds 5 and 6 reviewed the full final diff and were consecutive clean rounds. The existing public API test demonstrates the warning and retry behavior; no test of the assertion itself was added.

Publishing is manual; merging does not publish to RubyGems.

Closes #95
