Summary

Add a complete Unreal Engine 5 integration guide for the Lingo.dev CLI to docs/guide.md to streamline .po translation, .locres compilation, and runtime culture switching.

Changes

• Add “Unreal Engine – Lingo.dev CLI Integration Guide” to docs/guide.md:1–158
• Document Unreal Localization Dashboard setup (gather/export/import)
• Provide i18n.json for .po translation buckets using [locale]
• Include CLI flow ( npx lingo.dev@latest login and run )
• Explain .locres compilation and runtime culture switching (Blueprint and C++)
• Add troubleshooting and an end‑to‑end checklist for verification

Testing

• Documentation-only change; business logic tests are not applicable

• Manual validation steps performed:

  • Create widget with translatable text ( Hello, world )
  • Configure Game target; run Gather and export en.po
  • Add i18n.json and run npx lingo.dev@latest login → npx lingo.dev@latest run
  • Import es.po in Unreal and Compile .locres
  • Switch culture to es in PIE and verify localized UI

• All manual validation steps pass locally

Visuals

• N/A (documentation-only change; no UI/UX changes in the app)

Checklist

• Changeset added (not needed; docs-only)
• Tests cover business logic (N/A for docs; manual validation included)
• No breaking changes
