feat: add support for Redis Streams XINFO STREAM IDMP fields

[jinbum-kim]

closes #955

Port redis/go-redis#3685 XINFO STREAM IDMP fields to rueidiscompat.

• Add IDMPDuration, IDMPMaxSize, PIDsTracked, IIDsTracked, IIDsAdded, IIDsDuplicates fields to XInfoStream and XInfoStreamFull structs
• Parse the corresponding keys in XInfoStreamCmd.from() and XInfoStreamFullCmd.from()
• Add XINFO STREAM / XINFO STREAM FULL tests in testAdapterRedis86() to verify new fields on Redis 8.6+

---

Note

Low Risk
Low risk: adds new optional fields to XInfoStream/XInfoStreamFull and parses extra map keys, with tests updated to account for the additional data returned by newer Redis versions.

Overview
Adds support for Redis Streams idempotent production (IDMP) metadata in XINFO STREAM and XINFO STREAM FULL responses.

XInfoStream and XInfoStreamFull now expose IDMPDuration, IDMPMaxSize, PIDsTracked, IIDsTracked, IIDsAdded, and IIDsDuplicates, and the corresponding command decoders populate these fields when present. Tests are updated to ignore these fields in existing equality assertions and add new coverage verifying the IDMP values are returned and parsed.
