fix: surface handoff specialist activity\n\nQueue per-agent thinking updates from synchronous Copilot SDK session\nevents, flush them through the workflow runner, and promote handoff\ntargets to thinking immediately after handoff activity is emitted.\nThis fixes the UI case where downstream agents stayed on 'No status\nyet' during handoff patterns.\n\nAlso add targeted handoff diagnostics and regression tests.\n\nCo-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
