"""Verify intake kind hints are consistent and loaded from JSON single source.

Single source of truth is workers/lib/intake-hints.json.
This test ensures:
1. intake-hints.json exists, is valid JSON, and has all expected keys
2. Regex patterns in question_hints and failure_hints compile without error
3. Python (scripts/intake_kind.py) loads patterns from JSON
4. JS (workers/lib/utils.js) loads patterns from JSON
