Subject: [PATCH 01/10] WIP: Add chat view and view switching capabilities

This commit introduces a new chat view option in the social media app, alongside the existing thread view. It includes:

- New ViewProvider context to manage view state (chat/thread)
- Enhanced Reply and CanvasPreview components to support chat-message variant
- Added "chat" as a new sort criteria option in the dropdown
- Auto-switching between views based on sort criteria selection
- UI improvements for the chat view with appropriate styling

The changes allow users to toggle between thread and chat display modes for better conversation flow.

Note: This is work in progress and may need further UI refinements and testing.

Subject: [PATCH 04/10] refactor(frontend): improve Preview and Reply
 components architecture

BREAKING CHANGE: Reply component API changed to use variant prop instead of separate view/variant props

- Refactor Preview component into smaller, focused subcomponents
- Improve type safety with discriminated union types for preview variants
- Restructure Reply component to use CSS grid for better layout control
- Add chat message alignment support with left/right positioning
- Extract blur background into separate reusable component
- Fix typo in separateAndSortRects function name
- Add utility for combining Tailwind classes
- Improve code organization and readability throughout

Subject: [PATCH 09/10] feat(ui): improve layout and spacing in canvas replies

- Add consistent max-width and centering for canvas content
- Improve spacing between replies with dynamic grid gaps
- Update sticky header styling and background colors
- Refactor reply spacing logic for better visual hierarchy
- Move gap logic from Reply to Replies component for better organization

The changes enhance the visual consistency and readability of the canvas
replies section while maintaining responsive behavior.
