Missing STOP Hook Event After Final Tool Call

Bug Description
I have set up Claude Code hooks for all hook types.
If the last thing CC did was a tool call before handing back control to the user, no STOP hook event is send.
This makes it impossible to detect idle Claude Code sessions waiting for user input.\

Repro:

write hello to the todo list and do NOT output a message

⏺ Update Todos
⎿  ☐ Hello
☐ hello\
