Summary

  • Bump minimum Ruby version from >= 3.2 to >= 3.3 across all 64 gems
  • Remove Ruby 3.2 test steps from all CI workflows, move quality gates (yard, rubocop, coverage, build) to the 3.3 step
  • Update TargetRubyVersion in .rubocop.yml from 3.2 to 3.3 (verified zero new offenses)
  • Update README supported Ruby version documentation
  • Clean up dead Ruby version guard in sidekiq Appraisals

fix: use 3-digit Ruby version in markdown checks workflow
560fdf2 
Address review feedback: use "3.3.11" instead of "3.3" for
ruby/setup-ruby to match repo convention of 3-digit versioning.

Thanks @thompson-tomo — good catch on the 3-digit versioning. Fixed in 560fdf2, both occurrences now use "3.3.11" to match the repo convention.
