🔗 Linked issue

📚 Description

Adds a Korean (ko) locale to Canvas.

• New i18n/locales/ko/{global,navigation,contact,writing}.json — all keys translated from the English source (full parity, nested contact.subject_types included).
• Registered in i18n/locales/messages.ts (imports + ko block).
• Added { code: 'ko', name: 'Korean', language: 'ko-KR' } to i18n.locales in nuxt.config.ts, and /ko to the Nitro prerender routes so the Korean pages are statically generated like /en and /fr.

📝 Checklist

• I have linked an issue or discussion.
• I have updated the documentation accordingly.

Summary by CodeRabbit

• New Features
  • Added full Korean language support: translations for navigation, contact form, global UI, and writing/articles. Korean is now selectable across the app and site routes have been updated to include Korean, enabling complete localization for Korean-speaking users.

Inline comments:
In `@i18n/locales/ko/writing.json`:
- Line 8: The current localization key writing.readingTime contains "분 분량" which
duplicates the unit when rendered as "{{ page?.readingTime }} {{
$t('writing.readingTime') }}"; update the value of writing.readingTime to a
natural trailing unit/phrase that fits the "{number} {text}" pattern such as "분
소요" or "분 정도" so rendered output becomes e.g. "10 분 소요"; edit the
writing.readingTime entry accordingly.
