Extend the CI matrix to cover newer Ruby versions so we catch incompatibilities early. Adds Ruby 3.5 to the supported matrix and a non-blocking ruby-head build (continue-on-error) to surface upcoming breakage without failing the suite. Also sets fail-fast: false so one version failing doesn't cancel the rest of the matrix. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Ruby 3.5 never shipped as a stable release; the December 2025 release was branded Ruby 4.0. Point the matrix at the actual current stable (4.0) instead of the 3.5 preview line. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

terminal-table 4.0 requires unicode-display_width ~> 3.0, which conflicts with every rubocop that still supports Ruby 2.7 (needs < 3.0). Bundler silently backtracked rubocop to 0.7.2, which lacks rubocop/rake_task and broke the suite on 2.6/2.7. terminal-table 3.x works on Ruby 4.0, so the 4.0 bump was unnecessary.

Skunk::Config is a process-global singleton. config_test.rb mutated Config.formats but only reset in setup, so it leaked [:html, :json] into other files. Under minitest's randomized order this intermittently failed argv_test.rb's 'defaults to console format' expectation (seen on the Ruby 3.2 CI job). Reset Config in config_test teardown and before/after the argv formats tests so the suite is order-independent. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

The matrix currently tops out at Ruby 3.4. Ruby 4.0 shipped on December 25, 2025 (the 3.5 line never reached a stable release), so the suite should run against it. Running
headas well lets us catch incompatibilities before the next release.Notes
Opening as a draft to see how the suite behaves on the newer versions before marking it ready for review.
