refactor(cli)!: use mkdtempDisposable and require node >=24.4

[trivikr]

🔗 Linked issue

N/A

🧭 Context

The connector’s packageInit() flow created a temporary directory with mkdtemp() and then manually removed it in a finally block. Since this codebase now runs on Node.js 24.x, we can use the built-in disposable temp directory API instead of managing that cleanup ourselves.

📚 Description

This PR updates the CLI package init flow to use fs.promises.mkdtempDisposable() with await using in packageInit().

📝 Walkthrough

Walkthrough

The packageInit function in cli/src/npm-client.ts was refactored to use mkdtempDisposable and await using for temporary directory management, replacing the manual try/finally cleanup and switching filesystem operations and npm cwd to tempDir.path. Imports were adjusted accordingly. Additionally, cli/package.json tightened its Node.js engine requirement from >=24 to >=24.4.0.

I updated the engines field, I think we can get away with this since we're in pre-release :p
