When the claude CLI exits with a non-zero status, the previous error
handler only checked stderr. However, the CLI writes its output
(including error details) to stdout, especially when invoked with
--output-format json. This left the caller with only "exit status 1"
and no actionable information.
Now includes both stderr and stdout in the error message so the actual
failure reason is visible in logs.
