Add new skills for deploying ClickHouse servers

[hodgesrm]

This PR adds an overview skill for managing ClickHouse deployment, a skill to find out about different server builds, and skills that cover dev deployments using containers on docker compose or desktop Kubernetes.

The new skill organization is based on altinity-expert-kubernetes, which groups a large number of skills related to DBA operations under a single directory. Each directory includes a Makefile that builds skill releases and has targets to link skills directly to .claude during development.

To try out these skills, do the following:

git clone https://github.com/Altinity/altinity-skills
cd altinity-skills
git fetch -a && git checkout initial-deploy-skills
(cd  altinity-deploy-clickhouse; make link)
(cd  altinity-expert-kubernetes; make link)

Start claude in another directory and invoke /altinity-deploy-clickhouse-overview at the command line. Have fun!

This initial PR is structured so that it adds to existing skills with minimal/zero touchpoints.

we need to add github action deploy-skill.yaml and kubernetes-skill.yaml something like that https://github.com/Altinity/altinity-skills/blob/main/.github/workflows/profiler-skill.yaml
