docs: exit the poll loop on a jq failure too, not just a gh failure

Browse source 
Copilot review round 2 on #2272: a jq failure on an unexpected shape leaves n
empty, `[ "" -ge 1 ]` then exits non-zero, break never fires, and the loop
sleeps and retries forever — the same unbounded wait as the awk pipe, reached
from the other end. Verified locally: jq exits 5 and the test exits 1.

Propagate the jq failure, guard that n is numeric, and generalize the prose to
say every step which can fail exits rather than retries.
