indifferentketchup 5db6551361 feat(web): Phase 1-UX frontend — DiffPanel agent badges + resumed/new-session chip
DiffPanel renders a per-row agent badge (icon+label; null -> 'manual') + a 'Changes from X, Y' note when the pending set spans >1 agent. AgentComposerBar gains an optional sessionId prop -> resumed/history/new-session chip beside the Provider picker (gated, so BooChat callers are unchanged), driven by a new useAgentSessions hook (refetch on message-complete). providerIcon extracted to shared components/coder/providerIcons.tsx; api.coder gains agentSessions(sessionId); PendingChange type gains agent. web tsc clean.
