This explains the release cycle of Ubuntu.
Explanation of the Ubuntu release cycle
Released versions of Ubuntu are not beta versions. As one version of Ubuntu is released development begins on the next version. The development period is 26 weeks long. During that 26 week period the Ubuntu code goes through Alpha and Beta releases.
Ubuntu 25.10 is the current development version. This is the development roadmap.

You are a programmer. I am not. So, I ask: Does development ever stop?
It seems to me that you are looking for something that does not exist. You are not going to get a version of Ubuntu that does not have snap packages. Please explain to me how the existence of snap packages in an operating system will affect your work.
Just as Ubuntu is built on Debian so there are distributions built on Ubuntu. I have heard it rumored that some of those distributions do not come with anything snap packaged related.
