redisScan - Redis SCAN-based keyspace iterator

redisScan (v2.0.0) recursively iterates over all keys in a Redis instance using the recommended SCAN family of commands (SCAN, HSCAN, SSCAN, ZSCAN) and lists. It avoids the blocking KEYS * command, making it production-safe. Supports optional pattern matching and a callback per key or container element. Released as a single-version package with low update cadence. Differentiates from similar tools by supporting all data structures and providing detailed type/key/subkey/value info for each element.
