A failed tool result now leads its collapsed row with the chat's red
run-state dot (6px core, 10px halo) right after the chevron, so the
failure scans without expanding. The failure state comes from the fold's
`err` stamp OR the conversation snapshot's `isError` — the mismatch
matters: dsh only stamps the event envelope's `error` info
conditionally, while the snapshot block always carries `isError`. The
redundant ⚠ suffix on the tool-name chip is dropped (the dot marks
failures), and per-row conversation lookups are hoisted into one `conv`
for the merged condition.
