Fix task ID parsing for normalized single-line dispatch prompts

Splitting on newline alone left trailing text attached to the task
ID once normalizeSingleLinePreview folded newlines to spaces, so
getOrcaDispatchTaskId never matched in production status prompts.
Delimit on the first whitespace instead, and add regression tests
covering both the normalized and raw multi-line prompt shapes.
