Add the cp314 variant to the conda recipe now that conda-forge boost 1.91.0 ships libboost-python cp314 builds. Adds 3.14 to the python and python_abi lists in conda_build_config.yaml, lifts the meta.yaml runtime cap to <3.15, and bumps the conda.yml dev/build environment to match. Verified locally via conda render of the 3.14 variant: the dependency graph solves, pulling libboost-python 1.91.0 py314h3a4f467_0, python 3.14 cp314, and numpy 2.5 py314.

Description
Add a Python 3.14 (cp314) build variant to the conda package. conda-forge boost 1.91.0 now ships
libboost-pythoncp314 builds (e.g.libboost-python-1.91.0-py314h3a4f467_0on linux-64), which was the original blocker for 3.14 support.conda-recipe/conda_build_config.yaml: add3.14to thepythonlist and3.14 *_cp314topython_abi(zipped, so 5 variants), plus the matching render-check comment.conda-recipe/meta.yaml: lift the runtime cap frompython >=3.10,<3.14to<3.15.conda.yml: bump the dev/build environment cap to<3.15to stay consistent with the recipe.Details
Validated locally with
conda renderof the 3.14 variant — the dependency graph solves, pullingpython 3.14 *_cp314,python_abi 3.14.* *_cp314,libboost-python 1.91.0 py314h3a4f467_0, andnumpy 2.5 py314. cp314/noarch availability also confirmed for the other compiled/runtime deps (p4p 4.2.2, pyqt 5.15.11, pyzmq 27.1.0, pydm noarch). Theconda_build_libCI job will build all 5 variants end-to-end.
