Code Review

This pull request updates the CI workflows to use Python 3.14, preparing the project for the upcoming Python release. The changes correctly modify the build, lint, and test workflows, and update the CHANGELOG.md. The logic of replacing Python 3.13 with 3.14 in the main test matrix while keeping a dedicated 3.13 run on Ubuntu is sound. I've added one suggestion to improve the readability of the test workflow configuration by keeping the included test versions sorted.

@mike-hunhoff @williballenthin @mr-tz Hello can you please rerun only the failed test

[mike-hunhoff]

Hmm it looks like the Ubuntu 3.14 arm tests are never finishing. I don't see a specific failure, but it's running for >60 minutes, so I'm guessing a timeout. Thoughts @williballenthin @mr-tz ?

Hello @mike-hunhoff @mr-tz I’m looking for some assistance regarding the current CI failures affecting my PRs. It appears that test_fix262 is failing consistently, and I wanted to check if this is a known issue on the main branch. Any advice on how to proceed would be appreciated.

@kami922 we're back to where we were before with the tests failing after hanging for an extended period of time, e.g. testing 3.14 failed after 22 minutes on Ubuntu and 76 minutes on Windows. I'm not seeing any errors listed in the corresponding CI workflows - have you been able to run tests locally without issue? I'm concerned there is an issue specific to 3.14 that causes capa to run poorly...
