Squad init skips user confirmation before creating team #66

Problem

During Squad initialization (Init Mode), the coordinator frequently skips waiting for user confirmation after proposing the team roster. Instead of pausing at step 5 (Look right? Say yes, add someone, or change a role), it proceeds directly to creating the .ai-team/ directory structure.

This has been reported multiple times and is consistently reproducible. It almost always happens on initialization — not a rare edge case.

Expected Behavior

1. Coordinator proposes team roster with cast names
2. Coordinator STOPS and waits for user confirmation
3. User says 'yes', 'add someone', 'change a role', or gives a task
4. Only THEN does the coordinator create .ai-team/ structure

Actual Behavior

Steps 2-3 are skipped. The coordinator proposes the team and immediately creates the full .ai-team/ directory structure in the same response.

Root Cause Investigation

Needs research — is this a prompt structure issue, a platform behavior with long responses, or something else? See acceptance criteria.

Acceptance Criteria

• Root cause identified (prompt issue, platform behavior, or other)
• Fix implemented and tested
• Init flow reliably pauses for user confirmation
• Test cases added to verify the pause behavior
