Add logger runtime dependency for Ruby 3.5 compatibility

Issue #, if available: 51

Description of changes:
Added logger as a runtime dependency to fix Ruby 3.5 compatibility. The gem uses require 'logger' in multiple files but doesn't declare it as a dependency. In Ruby 3.5, logger will move from default gems to bundled gems, requiring explicit declaration to prevent load errors.
