Supported python version of conda install

[pcchen]

On ubuntu24.04, using miniconda, when I try conda install I encounter this problem:

conda create --channel conda-forge --name cytnx python=3.13  _openmp_mutex=*=*_llvm
conda install -c kaihsinwu cytnx
Channels:
 - kaihsinwu
 - conda-forge
 - defaults
Platform: linux-64

Solving environment: failed

LibMambaUnsatisfiableError: Encountered problems while solving:
  - package cytnx-0.9.0-py310h3fd9d12_0 requires python >=3.10,<3.11.0a0, but none of the providers can be installed

Could not solve for environment specs
The following packages are incompatible
├─ cytnx =* * is installable with the potential options

└─ pin on python 3.13.* =* * is not installable because it requires
   └─ python =3.13 *, which conflicts with any installable versions previously reported.

Pins seem to be involved in the conflict. Currently pinned specs:
 - python=3.13

Is there any difficult for upgrading the supported python version up to 3.13.5?

I also suggest to add "support matrix" to the README.md.

We have supported python 3.13 in the CI process, but we haven't released the latest version to Conda.
