IMHO, meld needs rebuild with python 3.14...

a) There is obviously no meld module present for python 3.14:
:; /usr/bin/python3.14 /usr/bin/meld file1.xml file2.xml
Traceback (most recent call last):
   File "/usr/bin/meld", line 98, in <module>
     import meld.conf  # noqa: E402
     ^^^^^^^^^^^^^^^^
ModuleNotFoundError: No module named 'meld'

b) Python 3.9 is still default one:
:; pkg mediator python
MEDIATOR            VER. SRC. VERSION IMPL. SRC. IMPLEMENTATION
python              local     3.9     vendor


Thanks anyway
