Subject: [PATCH] feat(feedback): wire feedback data into message rendering for
 history echo

Adds useThreadFeedback hook that fetches run-level feedback from the
messages API and builds a runId->FeedbackData map. MessageList now calls
this hook and passes feedback and runId to each MessageListItem so
previously-submitted thumbs are pre-filled when revisiting a thread.
