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.

v2.3 Phase 5. Provider management lives in Settings → Providers: lists every
registered provider with a status badge, enable/disable toggle (sends the full
override so a custom ACP entry's command survives the wholesale-replace PATCH),
per-provider refresh, and a plaintext diagnostic. The composer provider picker
now filters to enabled && (status==='ready' || 'loading') — disabled/unavailable
providers leave the picker and are managed only in settings; native boocode
always shows. Adds a curated ACP catalog + AddProviderModal (PATCH config then
subset refresh; the modal caps to the viewport with a single overscroll-contain
scroll region). Loading state uses a capped client poll (no WS frame).
