Integration test for config propagation through worker hierarchy.

Tests that config is properly merged and passed through:
    Parent CLI/Orchestrator
    └── CrawlWorker subprocess (via Process.env)

1. Snapshot.config (JSON field)
2. Crawl.config (JSON field)
3. User.config (JSON field)
4. Environment variables (os.environ + Process.env)
5. Config file (ArchiveBox.conf)
6. Plugin defaults (config.json)
7. Core defaults
