[BUG] Desktop app loses/orphans sessions after child process is force-terminated (DBG_TERMINATE_PROCESS) — "couldn't fork" on resume

What's Wrong?
Desktop app loses/orphans the previous session for a project after its CLI child process is force-terminated by Windows. On reopening the app, the last session isn't shown/resumable, and manually resuming it throws "couldn't fork".
What Should Happen?
The most recent session for a project should appear and be resumable after reopening the app, even if the CLI process exited abnormally rather than cleanly.

Work in a project session in Claude Desktop on Windows.
Close the app, or let the system sleep, while the CLI child process is still running (it gets killed with exit code 1073807364 / 0x40010004 = DBG_TERMINATE_PROCESS).
Reopen Claude Desktop, open the same project.
Previous session is missing or fails to resume ("couldn't fork").
