One-shot 提供商->提供者 normalization across src/i18n/messages/zh-CN.json
(679 substitutions) and bin/cli/locales/zh-CN.json (54), mirroring #8024's
zh-TW pass. Adds a versioned terminology glossary
(scripts/i18n/glossary/zh-CN.json), a protected-names list
(scripts/i18n/glossary/protected-terms.json), and a pure-function
consistency check (scripts/i18n/check-glossary-consistency.mjs,
npm run i18n:check-glossary) wired into CI as the i18n-glossary-zhcn job.
zh-CN added to the visual-QA harness default locales. Complements the
existing parity (check-ui-keys-coverage.mjs) and ICU (validate_translation.py)
gates without replacing them.
Add complete Swedish (sv) translation for all documentation files
including API Reference, README, and guides. Introduce automated
i18n QA infrastructure with visual regression testing across
multiple viewports and locales to validate translations.
