expose ports in sandbox pkg

[kcoopermiller]

Note

Adds SDK models/client methods and CLI commands to expose, unexpose, and list sandbox ports.

• SDK (prime_sandboxes):
  • Models: Add ExposePortRequest, ExposedPort, ListExposedPortsResponse in models.py and export from __init__.py.
  • Client APIs: In sandbox.py, add expose() (POST /sandbox/{id}/expose), unexpose() (DELETE /sandbox/{id}/expose/{exposure_id}), and list_exposed_ports() (GET /sandbox/{id}/expose) to both SandboxClient and AsyncSandboxClient.
• CLI (prime_cli):
  • New commands: sandbox expose, sandbox unexpose, sandbox list-ports with table/JSON output, leveraging new SDK APIs.
