Title: Stop hooks not executing after responses despite proper configuration

Description:

• Expected: Stop hook should run after every Claude response per .claude/claude.json configuration
• Actual: Hook only runs sporadically/not at all during conversation
• Configuration: Stop hook properly configured with --notify flag in claude.json
• Evidence: Debug file shows hook ran at 12:34 but no entries for subsequent responses
• Impact: TTS notifications and logging features are broken

Steps to reproduce:

1. Configure Stop hook in .claude/claude.json with --notify flag
2. Have conversation with Claude
3. Check if hook runs after each response (it doesn't)

This appears to be a core hook execution issue affecting the fundamental hook system functionality.
