* fix(middleware): fix positional fallback consuming unrelated todo when same-content list is exhausted

When next_todos contains the same content string twice (e.g. two "A"
entries), the first iteration pops the matching previous todo from
previous_by_content["A"], leaving an empty list. The second iteration
finds that empty list, treats it as falsy, and sets previous_match=None.
The positional fallback then fires unconditionally — consuming
previous_todos[index] even if it holds a completely different entry
(e.g. "B"). That marks "B" as matched, so the final loop never emits
a todo_remove action for it.

Fix: guard the positional fallback with `content not in previous_by_content`
so it only fires for genuinely new content (the key was never in previous),
not for same-content entries whose list has simply been exhausted.

Add a regression test to _build_todo_actions covering this exact case.

* style: ruff-format the token usage middleware test
