[Bug] PermissionRequest hook not fired for agent-teams teammates outside tmux

Bug Description
tldr; teammates in agent-teams do not fire PermissionRequest hook because ask about it to Orchestrator instead of a human (actually expected, but answer to this still will do a human). This problem exists only when team of agents run outside of tmux.

Steps to reproduce:

1. Start claude --dangerously-skip-permissions with turned on agent-teams OUTSIDE of tmux
2. Ask a prompt:

I want you do only next steps:

1. Create a team of agents (your task will be set later, dont ask/research for now)
2. Enter plan mode
3. Spawn a teammate and ask him for curl https://anthropic.com

Dont do anything else. Follow a plan step by step.

Expected behavior:
No questions to Orchestrator OR PermissionRequest hook fired properly with acceptance the answer via stdin.
