expose ports - tcp

[kcoopermiller]

Note

Adds TCP/UDP port exposure support to SDK/CLI, a global list-ports view, an SSH connect helper, and a demo script.

• SDK (prime-sandboxes):
  • ExposePortRequest: add protocol (default HTTP).
  • ExposedPort: add external_port (for TCP/UDP).
  • SandboxClient/AsyncSandboxClient:
    • expose(...) accepts protocol.
    • New list_all_exposed_ports() to list exposures across all sandboxes.
• CLI (prime sandbox):
  • expose command: support --protocol/-p (HTTP/TCP/UDP); show protocol and external_port (when applicable).
  • list-ports command: sandbox ID optional; when omitted, lists all exposures across all sandboxes; enhanced table columns.
  • New ssh command: exposes TCP port, connects via ssh, and auto-cleans exposure.
• Examples:
  • Add examples/sandbox_port_expose_demo.py demonstrating HTTP and TCP exposure, verification, listing, and cleanup.
