Error Handling Skill

Unified error handling system for DF. Use when adding API endpoints, modifying error handling, or adding frontend API calls.

Prerequisites: Read docs/dev-guides/7-unified-error-handling.md before changing API error behavior. Read docs/dev-guides/2-log-sanitization.md when the work involves logging, credentials, external services, or DataLoaders. If your work introduces new error handling patterns or conventions, update this file and related dev-guides accordingly.
