Nested Team History for Members
===============================

Demonstrates `add_team_history_to_members` for nested teams: when a parent team
delegates to a nested sub-team, the sub-team is given ITS OWN prior history
(filtered by the sub-team's id) rather than the root team leader's history.

Key concept: `add_team_history_to_members=True` injects a text summary of past
runs into each delegated task. For a nested sub-team, that summary is now scoped
to the sub-team, so it can recall what it specifically worked on across turns.

Note: a parent can delegate directly to a leaf agent inside a sub-team, so the
instructions below force delegation to the sub-team as a unit — that is the path
that receives the sub-team's own history.
