"""
Production readiness check — the "production" gate of the agent
build/deploy workflow. Verifies: package imports, API route surfaces,
registry cross-references, test suite health, docker/deploy assets.

Usage:
    python3 scripts/production_check.py

Exits 0 (PASS) or 1 (FAIL) with a structured report.
