fix(redis): Implement ChatMemoryRepository interface and fix test connectivity

[bsbodden]

@markpollack cc/ @joshlong @ThomasVitale @tzolov with the help of Josh I made some modifications requested for the new changes upstream and the issues with the TestContainers connectivity. I will follow up with an addition to break the functionality into separate modules and do some more clean up. But hopefully this PR will allow you to continue the review. Thanks!

Refactor Redis-based chat memory implementation to:

• Implement ChatMemoryRepository interface as requested in PR feat(redis): Add Redis-based semantic caching and chat memory implementations #2295
• Fix Redis connection issues in integration tests reported in PR WIP - Redis/semantic caching advisor and chat memory #2982
• Optimize conversation ID lookup with server-side deduplication
• Add configurable result limits to avoid Redis cursor size limitations
• Implement robust fallback mechanism for query failures
• Enhance support for metadata, toolcalls, and media in messages
• Add comprehensive test coverage with reliable Redis connections

Thank you for taking time to contribute this pull request!

@markpollack I am almost there with a modularized version of the PR... a few more hours

@markpollack I think I got everything in place now. Let me know if I need to do anything else to get this going. Cheers!

I am looking forward to this feature(semantic cache). When will it be available🫡?

Hey all, this feature is a great win. Wondering when this is planned to be released? Would appreciate the chance to use Redis as my short term storage solution!

[ssamir0602]

@markpollack Hey, does this mean that SpringAI will not be moving forward with a Redis impl for chat memory?

[markpollack]

Hi. I think I closed this newer PR by mistake, keeping the older one open. I'll close #2295 and reopen this one

[markpollack]

I can't seem to set the status of the PR to open again, it seems you need to do it @bsbodden

[markpollack]

i'll be making a new PR that is compatible with the current code base structure, will link once it is posted.

@markpollack I can't seem to be able to re-open the PR. I'll try a force push to see if that "wakes it up" :-)

@markpollack I pushed it as a new PR here #4982
