🤖 Augment PR Summary

Summary: This PR adds client support for Redis 8.5+ HOTKEYS commands and adjusts CI to test against a custom Redis build tag.

Changes:

• Introduced HotkeysMetricsTypes enum and added hotkeys_start/stop/reset/get methods under management commands.
• Registered a response callback for HOTKEYS GET to parse its key/value reply structure.
• Explicitly marks HOTKEYS commands as unsupported for cluster clients (sync and asyncio) by raising NotImplementedError.
• Added comprehensive sync and asyncio tests covering HOTKEYS start options, stop/reset behavior, and GET response fields (decoded and raw).
• Updated the composite GitHub Action to map custom Redis image tags to a numeric Redis version for determining the major version.
• Adjusted the integration workflow matrix/environment to use the custom Redis tag and its mapped version.

Technical Notes: The new HOTKEYS API is guarded by a server-version skip (8.5.240+) in tests, and HOTKEYS GET is treated as an array-wrapped response for aggregation-style replies.
