Team Time Travel

Rewind a team run to an earlier point and resume. The boundary is chosen with continue_from:

"end" — keep the whole transcript
"last_user" — keep through the last user message, drop the post-user tail
K (int) — keep messages[:K]

A COMPLETED team run auto-forks into a new sibling so the source remains a durable record of the completed model loop. fork=True makes that explicit and also works on non-completed runs — run-level fork is time-travel that keeps both the original and the new line in the same session. Boundaries are snapped to a tool-call-safe index so the resumed transcript is never left with an orphaned delegation.

Example	What it shows
`01_continue_from.py`	`continue_from="end"`, `"last_user"`, and the numeric `K` form. COMPLETED runs auto-fork.
`02_fork_run.py`	`fork=True` + `continue_from` for an explicit non-destructive sibling team run.
