Log typescript errors on build dictionaries

[aymericzip]

A PR (110) was started to improve visibility of missing translations by logging TypeScript errors (e.g. unresolved keys in t() functions) during the build.

However, this change introduced undocumented side effects that must be resolved.

Tasks

• Investigate and document the side effects introduced by the PR.
• Run pnpm intlayer build to reproduce and trace the issue.
• Ensure missing translation errors (from .js, .ts, .jsx, .tsx, or .json content declaration files) are correctly logged during the build.
• Ensure the dictionaries build works as expected, including for all supported content file formats docs.
• Ensure the overall application build process is unaffected.
• Push an updated PR that resolves these issues.
