Team Regenerate

Redo the last response of a team run. regenerate=True drops only the trailing assistant answer, keeps intermediate tool exchanges (member delegations are not re-run), and re-generates a fresh final answer.

Regenerate always forks — a new team run_id with fresh metrics; the source is always retained. replace_original controls only history visibility of the source:

default (replace_original=True) — source marked REGENERATED and hidden; new run replaces it
replace_original=False — source stays COMPLETED and visible, so both attempts show

Member rows the original team produced stay attached to the original team — fork replays the team's own model loop with a new run_id; delegated work that already happened is a fact of history, not state to copy.

Example	What it shows
`01_regenerate.py`	`team.continue_run(regenerate=True)` — new `run_id`, fresh metrics, original team and members untouched.
