Avoid auth-sanitizer top-level namespaces

[pboling]

Summary

• load auth-sanitizer through an isolated internal loader
• keep sanitizer integration under the OAuth::TTY namespace
• prevent requiring oauth/tty from adding top-level Auth or AuthSanitizer constants

Testing

• bundle exec rspec spec/oauth/tty/auth_sanitizer_spec.rb spec/oauth/tty/command_spec.rb

Pull request overview

This PR updates the auth-sanitizer integration so require "oauth/tty" no longer introduces top-level Auth / AuthSanitizer constants, keeping the sanitizer loaded and referenced under the OAuth::TTY namespace to avoid downstream constant collisions.

Changes:

• Added an internal isolated loader (OAuth::TTY::AUTH_SANITIZER) to load auth-sanitizer without defining top-level namespaces.
• Updated Command (and its RBS signature) to include OAuth::TTY::AUTH_SANITIZER::FilteredAttributes instead of Auth::Sanitizer::FilteredAttributes.
• Bumped the gem version to 1.0.8 and tightened the auth-sanitizer dependency to >= 0.1.3.
