Added

• Many more tests

Fixed

• RSpec shared examples for Ast::Merge::DebugLogger now handle Ruby 4.0+ where benchmark is a bundled gem
  • The #time logs start and completion with timing test now checks BENCHMARK_AVAILABLE constant
  • When benchmark is available: expects full timing output with “Starting:”, “Completed:”, and real_ms
  • When benchmark is unavailable: expects warning message about benchmark gem not being available
  • Fixes CI failures on Ruby 4.0.0 for downstream gems (e.g., bash-merge) using the shared examples
