Unit tests fail with minitest 6.1.0 (bare hash passed to must_equal) #95

CI is red on every Ruby version since minitest 6.1.0 (released 2026-11-06). The Gemfile and gemspec leave minitest unpinned, so CI now installs 6.1.0; the last green run on main was 2026-10-21.

13 unit tests fail with Use assert_nil if expecting nil., for example:

• test/unit/transloadit/test_assembly.rb:33 — _(@assembly.steps).must_equal foo: 1
• test/unit/transloadit/test_assembly.rb:37 — _(@assembly.to_hash).must_equal(auth: …, …)
• test/unit/transloadit/test_step.rb:32 and :44

minitest 6.1.0 "Removed ruby2_keywords delegation workaround from Spec". A bare hash literal passed to must_equal (must_equal foo: 1) is now taken as keyword arguments instead of the expected value, so the expectation compares against nil. Wrapping the expected hash in braces (must_equal({foo: 1})) should fix it; pinning minitest < 6.1 would be a stopgap.
