Grok worktree show stays alive after the creator exits
grok worktree show printed Status: alive. The creator PID on that line was not a running process. grok sessions list exited 0 and printed No sessions found. The session id began with pager-. A search of the grok home found that id in the worktree registry and nowhere else.
That is the line that will mislead a wrapper. grok worktree create exited 0, wrote one path to stdout, and wrote nothing to stderr. The sessions page this binary installed on first launch says create does not start a session, and that the path is the only stdout, so a command substitution can change to that directory. Both of those sentences held. The registry row did not. Show still reported a session id, a creator PID, and a status of alive after the create process was gone.
