[Enhancement] Python 3.14 support

[Houbein]

Is your enhancement request related to a problem? Please describe.
Currently trying to load testsets with robotcode in VS-Code under Python 3.14RC3 does not work.
I am unsure if this is a robotcode problem, or with it's underlying depencendies (VS-Code is not being very helpfull with error messages). But I thought I would mention it here.

Describe the solution you'd like
Python 3.14 support.

I will do this right after the official Python 3.14 is out.

I did run the unit and regression tests for RobotCode with an alpha version of Python 3.14 some weeks ago and everything runs fine.

Question for you: can you run your tests with Python 3.14?

[Houbein]

Yes running our testset with RobotCode through commandline works fine.
It seems to be purely a problem with the extension in VS-Code. The run buttons do not appear, unless I select the "Testing" tab, then they do appear but using them does nothing and just gives the message "The test run dit not record any output.".
The "Robot Framework" field in the lower right corner is also stuck on loading indefinitely.
