feat: Add Actor runs API, dataset API, KV-store

[jirispilka]

• fix: Use a new API to get Actor default build`
• feat: add get-actor and get-user-runs-list
• feat: add dataset, Actor runs, fix tests

Closes: #79

Ideally, when using Actorized MCP servers we should add information about dataset and Actor run into context but for that we need to fix this issue first: apify/tester-mcp-client#67

Just a minor comment otherwise LGTM 👍

@MQ37 This PR has grown quite a bit — sorry about that! Once again, we ended up working on the same part of the code, and when I started fixing the unit tests, I went down a rabbit hole and couldn’t stop myself. 😅

I really like the tests you added — they’re super helpful, thanks!

That said, there’s one test I believe is tied to the reset function, which always loads the default Actor. So even when the server is called with a specific Actor selected, the default one still gets loaded — which shouldn’t happen.

We’ll need to fix that.

Also, I ran into an issue where, after the test completed, the process was still hanging around and consuming 100% CPU.

If you could please review again. Mainly the test suite and mcp/server.ts 🙏🏻

Nice refactor, thank you 👍 Just one issue with the Actorized MCP server tools listing otherwise LGTM

LGTM 👍 We will fix the test reset func later
