How to build and use Python 3.14.x on FreeBSD as the default version

First important thing is to add needed pieces in /etc/make.conf file

DEFAULT_VERSIONS+=python3=3.14
DEFAULT_VERSIONS+=python=3.14

The you must get working copy of feature python314 port from here.

Here is my example to upgrade from Python 3.13.8 to 3.14.0:

# sh
# portmaster -o lang/python314 python313
# REINSTALL="$(pkg info -oq '*py313*')"
# pkg delete -f "*py313*"
# portmaster $REINSTALL
# REBUILD=$(pkg query -g "%n:%dn" '*' | grep py3 | grep -v py314 | cut -d : -f 1 | sort -u)
# portmaster $REBUILD
# REBUILD2=$(pkg list | grep python-313 | xargs pkg which | awk '{print $6}' | sort -u)
# portmaster $REBUILD2

There is visible difference in performance after the upgrade.
