Improve translation workflow to avoid unnecessary file reads (#5126)

* dotroo: improve translation workflow to reduce unnecessary file reads

Update translation workflow guidelines to use search_files instead of reading
each translation file individually. This approach is more efficient and
reduces context token usage while maintaining translation accuracy.

The improved workflow:
- Uses search_files to find JSON structure in translation files
- Creates proper context for apply_diff without reading every file
- Only reads specific files when their structure differs
- Validates changes with the missing translations script
