Adds the missing Apps tab to the v2 UX specification. Apps are the subset
of tools whose `_meta.ui.resourceUri` advertises a UI resource (per
`@modelcontextprotocol/ext-apps`). The screen mirrors the legacy v1 layout:
a sidebar of apps and a right pane that toggles between an input form
(before launch) and the embedded MCP App via `AppBridge`.
- v2_ux.md: add `[Apps]` to the navigation tab list and a new "Apps Screen"
subsection with both states (input form / running app).
- v2_ux_features.md: full Apps Screen feature spec — ASCII diagrams,
detection rule, presentational contract for `AppsScreen` / `AppRenderer`
(imperative ref shape so the screen stays "dumb" and the wiring layer
drives the bridge).
- v2_screenshots.md: link the two reference PNGs from the legacy v1 client.
- v2_ux_storybook.md: add `AppListItem` (2.3a), `AppDetailPanel` (2.5a),
`AppRenderer` (2.5b), and `AppsScreen` (3.2a); update Build Order.
Implementation work tracked on the v2 board: #1260–#1264.

- Rename ResourceTemplateInput to ResourceTemplatePanel with panel layout
(title header, URI with live variable preview, labeled inputs, Read Resource button)
- ResourceTemplatePanel manages its own variable state via useState;
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)
