Close the surviving setup terminal before runForThread opens it again.

If the checkout is deleted while its setup shell is still open, the shell keeps the deleted directory as its working directory. A later recovery calls runForThread, which opens the same setup-${script.id} terminal ID. TerminalManager.open reuses that session when its cwd, worktreePath, and env strings match. The recreated path has the same string, so the old shell is reused. The setup command is then written to that shell and can run with the deleted directory as its working directory. A setup shell stays open after a nonzero exit, so a failed setup can leave this state. The failure needs an external deletion while the shell is still open.

Close the existing setup terminal for this terminalId in runForThread before terminalManager.open. Place the close before observeTerminalCompletion subscribes, so the subscription does not receive events from the old session.

Review comment at @apps/server/src/orchestration-v2/ProviderTurnStartService.ts
at line 692:
In setupScripts.runForThread, close any existing terminal session for the setup
terminalId before terminalManager.open reuses or creates it, and do so before
observeTerminalCompletion subscribes. Use the existing terminal-close mechanism
and preserve the current setup flow for newly opened sessions.
