/**
 * Deep Tests for Plugins, Transfer, Production, Runtime, Update, Config, and Appliance modules.
 *
 * Covers:
 *  - Plugin discovery, search, install/uninstall lifecycle
 *  - Transfer serialization round-trips (CFP format)
 *  - Anonymization (PII detection and redaction)
 *  - IPFS client helpers (CID/IPNS validation, gateway URLs, hash)
 *  - IPFS upload helpers (gateway URL, IPNS URL, service status)
 *  - Plugin Store high-level API
 *  - Transfer Store search, registry, and helpers
 *  - Config adapter (system <-> v3)
 *  - Production utilities (circuit breaker, rate limiter, retry, error handler, monitoring)
 *  - Update system (validator, rate-limiter)
 *  - Benchmark infrastructure
 *  - Type exports completeness
