feat: add uv runner

[gouzil]

motivation

I need a solution that can install dependency packages in real time, and I don't want it to cause dependency package conflicts.

feat

This pull request introduces support for a new uv¹ runtime environment in the dify-sandbox project. The changes include adding build scripts, runtime initialization, dependency management, and configuration updates to integrate the UV runtime alongside existing Python and Node.js environments.
