[FEATURE] Use permission prompt tool in interactive mode

Claude 4 is good enough that I mostly just keep an eye on it to steer.

I wanted to do this while AFK, so I setup an MCP server with Whatsapp integration to message me for permission prompts.
However, --permission-prompt-tool appears to only be used with -p, and since network access is disabled, a bunch of the stuff it would be useful to give permission for (curl, etc) is not allowed anyway.

Feature requests:

1. Use the permission prompt tool in interactive mode, so I could step away for a while and approve/deny Claude's permission prompts remotely. Another use case for this would be a more detailed allow/deny list e.g. whitelisting specific domains or sub paths, which is not supported by the Claude config at present.
2. Flag to allow network access for -p (maybe requiring a permission prompt tool so users can run at their own risk).

Thank you!
