- Extract ResourceControls group component from ResourcesScreen:
title, search, list-changed indicator, and three-section accordion
(URIs, Templates, Subscriptions) with per-panel ScrollArea.Autosize
- Refactor ResourcesScreen to sidebar+panel Flex layout matching
HistoryScreen/LoggingScreen pattern (ScreenLayout, Sidebar, SidebarCard)
- Each accordion panel dynamically computes max height based on how many
sections are open, dividing available space evenly
- Accordion uses controlled state (value/onChange) to track open sections
- Sidebar card sizes to content naturally (compact when collapsed,
grows with open sections, capped by scroll areas)
- Right panel wrapped in ScrollArea.Autosize for long content
- Add AllSections story with 20 URIs, 7 templates, 8 subscriptions
- Add more templates and subscriptions to ConnectedView ResourcesActive

- Redesign TaskCard to match v1 Task Details panel layout:
header with task ID + status badge + cancel button,
always-visible summary row (Status, Last Updated, Created At, TTL)
with Expand/Collapse button, expandable section with status message,
progress bar, error, and Full Task Object JSON viewer
- Add TaskControls group: search input + status filter dropdown +
Refresh/Clear History buttons (mirrors HistoryControls pattern)
- Add TaskListPanel group: scrollable panel with ListToggle for
expand/collapse all, splits tasks into Active/Completed sections
with counts, filters by search text and status
- Refactor TasksScreen to sidebar + panel layout matching HistoryScreen:
manages search/filter state internally, flat tasks array
- Simplify TaskCard callbacks to just onCancel
- Extract named .withProps() subcomponents (HeaderLeftGroup,
HeaderRightGroup, SectionTitle, SummaryRow, DetailRow) for
AGENTS.md compliance
- Update all stories (TaskCard, TaskControls, TaskListPanel,
TasksScreen, ConnectedView)

- Rename ResourceTemplateInput to ResourceTemplatePanel with panel layout
(title header, URI with live variable preview, labeled inputs, Read Resource button)

single onReadResource(uri) callback returns fully resolved URI
- Extract ResourceSubscribedItem group component with name, timestamp, and
subtle Unsubscribe button
- Add hover state to listItem variant via theme classNames + App.css pseudo-selector
- Add Refresh button to ResourcePreviewPanel
- Refactor ResourcesScreen callbacks: onSelectUri, onSelectTemplate,
onReadResource, onSubscribeResource, onUnsubscribeResource replace
per-item onClick/onUnsubscribe props; screen wires callbacks to children
- Define data-only types (ResourceItem, TemplateListItem, SubscriptionItem,
SelectedResource, SelectedTemplate) separating data from callbacks
- Extract named .withProps() subcomponents (FooterRow, AnnotationGroup,
ActionGroup, Spacer) for AGENTS.md compliance
- Update all stories (ResourceTemplatePanel, ResourcesScreen, ConnectedView)

- Remove ConnectionService/ExecutionService from core interfaces
(connection/execution state managed by React Context per spec text)
- Remove Memory implementations from core package

Closes#983
Proposes a hybrid state management architecture:
- Zustand for UI preferences, logs display, playground state, testing profiles
- Keep useReducer + Context for connection/execution state machines
- Repository interfaces remain storage-agnostic for proxy API integration
Includes detailed analysis of storage options (Zustand, Redux, Jotai,
Context+useReducer, TanStack Query, Valtio) with pros/cons comparison.
