## Summary by cubic
Adds multi-component selection in the preview and sends all selected
components to chat for targeted edits. Updates overlays, UI, and IPC to
support arrays, smarter context focusing, and cross-platform path
normalization.
- **New Features**
- Select multiple components in the iframe; selection mode stays active
until you deactivate it.
- Show a scrollable list of selections with remove buttons and a Clear
all; remove from the list or click an overlay in the preview to
deselect. Sending clears all overlays.
- Separate hover vs selected overlays with labels on hover; overlays
persist after deactivation and re-position on layout changes/resizes.
- Chat input and streaming now send selectedComponents; server builds
per-component snippets and focuses their files in smart context.
- **Migration**
- Replace selectedComponentPreviewAtom with
selectedComponentsPreviewAtom (ComponentSelection[]).
- ChatStreamParams now uses selectedComponents; migrate any
single-selection usages.
- previewIframeRefAtom added for clearing overlays from the parent.

## Summary by cubic
Add a shortcut to quickly activate the component selector from the
preview. Use Meta+Shift+C on macOS and Ctrl+Shift+C on Windows/Linux.
- **New Features**
- Added useShortcut hook to handle key combos and prevent default on
match.
- Wired shortcut in PreviewIframe with OS detection for Meta vs Ctrl.
- Forwarded keydown events from the iframe to the parent via postMessage
(dyad-shortcut-triggered) so the shortcut works inside preview content.
