Add automated Conda publishing to release workflow

[harryswift01]

Summary

Add Conda packaging and automated publishing to the CCPBioSim Anaconda.org channel as part of the existing release workflow.

Changes

Conda recipe added (conda-recipe/meta.yaml)

• Added a noarch: python conda-build recipe for CodeEntropy.
• Includes runtime dependencies mirroring pyproject.toml and defines the CodeEntropy CLI entry point.
• Added basic import/CLI smoke tests in the recipe.

Release workflow updated to publish to Anaconda.org

• Extended the release GitHub Actions workflow with a conda job.
• Job updates the recipe version from the workflow input, builds the conda package, and uploads it to the CCPBioSim Anaconda.org organisation.
• Uses ANACONDA_TOKEN GitHub secret for authentication.

Pre-commit updated to allow Conda Jinja recipe

• Updated .pre-commit-config.yaml to exclude conda-recipe/meta.yaml from check-yaml (Conda recipes contain Jinja templating and are not valid strict YAML).

Impact

• Adds an official Conda installation path (conda install -c CCPBioSim CodeEntropy) for users in Conda/HPC workflows.
• Automates Conda publishing during releases, keeping PyPI and Anaconda distributions in sync.

The changes in this PR bring about our first software package being added to our channel. This is a great first step in bringing wider availability since conda is more popular than pypi and virtual env. Workflow looks like it has the necessary steps and the smoke tests are a nice touch.

Only change I would request is that we add the conda way to virtualise and install to the getting started documentation. If you were preferring to do this after the workflow was verified and in a separate PR then let me know and I''l change this to approve

That's a good idea, I can add that to the docs now.

All looks great! Thanks for fixing the logo in the main readme too.
