renderAgentResult and the live-progress sibling cast
extractedToolData?.yield to Array<{ data }> and called ?.map without
checking the actual runtime shape. Optional chaining only short-circuits
on null/undefined, so any stray non-array value (a single yield object
landing in the slot) made .map undefined and threw
TypeError: completeData?.map is not a function — taking down every
`review` task render.
Both sites now route through a new normalizeYieldData helper (next to
normalizeReportFindings) that returns an array of yield records: it
preserves arrays unchanged, wraps a single object as a 1-element array
so the verdict still renders, and drops primitives. Added a regression
test exercising the result branch, the progress branch, the primitive
fall-through, and the canonical array shape — all of the failing-branch
ones reproduce the crash on the pre-fix renderer.
Fixes#1987
