[bug] Experimental agent team mode: "q.toolUseContext.getAppState is not a function" when sub-agent triggers permission prompt

Summary

In experimental agent team mode (CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 + teammateMode: "tmux"), a runtime error appears in the sub-agent pane every time its tool use hits the permission-prompt code path.

Error

ERROR q.toolUseContext.getAppState is not a function
file:///opt/homebrew/lib/node_modules/@anthropic-ai/claude-code/cli.js:8493:15619

Location in bundled CLI

cli.js line 8493, inside the React hook that emits tengu_tool_use_show_permission_request:

let Y = q.toolUseContext.getAppState().toolPermissionContext.mode;
d("tengu_tool_use_show_permission_request", { ... });

On the sub-agent side, q.toolUseContext has no getAppState() method, so this throws before the permission UI can render.

Steps to reproduce

1. ~/.claude/settings.json → {"env":{"CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS":"1"}}
2. ~/.claude.json → "teammateMode": "tmux"
3. Start claude inside tmux, form a team (e.g. lead vault-organizer + sub-agents scanner-a, scanner-b spawned via --agent-id ... --team-name ... --parent-session-id ...).
4. Lead dispatches a Bash task to a sub-agent that needs permission (e.g. find "$DIR" -type f -name "*.md").
5. Sub-agent pane prints Waiting for team lead approval, and the ERROR above appears on the sub-agent pane at the same moment.

Environment

• claude-code: 2.1.112 (global npm install at /opt/homebrew/lib/node_modules/@anthropic-ai/claude-code)
• macOS: 26.3 (25D125), Apple Silicon
• node: v25.6.1
• tmux: 3.6a

Expected

Sub-agent should forward the permission request to the team lead without calling getAppState() on a context that doesn't have it.

Actual

TypeError logged in sub-agent pane each time a tool use reaches the permission-prompt branch.
