new: Add set of Memgraph and Memgraph Lab skills

[tonilastre]

I've added a set of new skills, both for Memgraph and Memgraph Lab (GSS for now).

There are already a bunch of skills here, but not all make sense in Agent Chat's automatic sync (e.g., building Rust query modules or memgraph ui design), so I've added a new field integrations in frontmatter so we can filter by that when the actual sync in the Lab happens. Lab will check the repo and only pick those skills that have memgraph-lab with the correct version in the integrations list.

If you have any other idea how to name that field, feel free to recommend it.

Let's chat live about this.

https://agentskills.io/skill-creation/evaluating-skills How we should evaluate?
https://github.com/cloudflare/skills/blob/main/skills/cloudflare/SKILL.md How we should organize?
https://code.claude.com/docs/en/plugins-reference - How to distribute?

These are two separate skills IMO

Strange name for a skill 🤔 memgraph-cypher-/debug/fix/rewrite

Maybe it is me, but write is like write operation to me, maybe even memgraph-cypher-syntax

@antejavor, this is just so you are aware when you are back.

I've applied your comments: Changed the naming of some skills (e.g. write-cypher) and split the one with indexes and database administration into two.

Along with that, I've added a plugin system for Cursor, Claude and Lab. Cursor and Claude don't really matter now because it works only after you register to their marketplace. I've added a registration for Cursor for now and I am waiting for approval.

Skills have been moved to folder skills so we can add prompts, commands, and other utilities in the future (similar to Cloudflare). I haven't structured skills into a better organization because we don't have so many of them now to force the organization so I would leave it as is until we have a decent number of skills.
