v0.0.14

• Feat: expose variant and flag_metadata on EvaluationDetails (qfg-9dbl). OpenFeature's EvaluationDetails Ruby return type now carries the variant name and the flag-level metadata hash alongside the resolved value/reason. Brings sdk-ruby to parity with the other SDKs' detail surfaces and lets host apps (incl. the Ruby OpenFeature provider) read variant/metadata without re-fetching the config.
• Test: regenerate integration tests from rubocop-clean templates (qfg-vrck). The integration suite under test/integration/ is now generated from templates that pass bundle exec rubocop on first emit, so future regenerations don't trigger a follow-up autofix commit.
