What
When the process running a session crashes during its setup phase, Claude Code builds a synthetic error result describing what happened. That error-building function now accepts a setupTerminal option, and when it's set, the resulting runner_exit detail for a setup-phase failure includes terminal: true.
Why
This lets whatever consumes these error reports distinguish a setup failure that can't be recovered from other, presumably retryable, setup failures.
