Support Keras 3

[mhucka]

TensorFlow Quantum currently supports only Keras 2. The broader TensorFlow ecosystem has transitioned from Keras version 2 to Keras version 3. It would be good to update TFQ's Keras support to work with Keras 3.

Hey @mhucka happy to give this a shot. Where would you point at as a starting point? I will read keras 3 docs and compare to 2, review how it's curretnly used across the repo, and suggest a short pr if assigned. Thanks.

@rosspeili Thanks for offering. I've assigned it to you.

I regret I'm not familiar enough with the frameworks to have a good recommendation, unfortunately. My naive approach would probably be to install keras 3 in a python venv, then try to run tests and see what breaks. It might be pretty bad.

It might also be worth asking Gemini. Maybe something like telling it to read the documentation for Keras 2, Keras 3, and and the TFQ documentation, then formulate a plan for how to go about updating the code base. Then again, there's a risk it will just blow through your token budget, due to the amount of text involved …

Thanks a lot @mhucka, I will do a comparison locally with local ollama models via continue plugin, so no token burning, but appreciate the heads up <3 I will share a short report here once I have a clear bird's eye view <3
