This PR radically overhauls the video editor to provide a "CapCut-like" experience.

Key Features

  1. Multi-Track Timeline: Transitions from a simple slider to a fully functioning multi-track non-linear editor (NLE) timeline supporting Video, Audio, Text, and Sticker layers. Features drag-and-drop clip adjustment, track management, and zooming.
  2. Context Menu: Timeline clips now support right-click context menus for common actions like Splitting, Copying, Pasting, Duplicating, and Deleting.
  3. Dynamic Resizable UI: The entire editor workspace is now composed of resizable panels, allowing users to freely adjust the sizes of the preview window, timeline, and property sidebars.
  4. Advanced Preview Engine: A new rendering component that orchestrates multiple HTML5 <video> and <audio> tags synchronized perfectly with the timeline's currentTime playhead.
  5. AI Tools Integration: An AI magic panel was added to simulate generating auto-captions and performing auto-cuts via the system's selected LLM/STT configurations.
  6. Unified Properties Panel: A single, context-aware sidebar updates dynamically to show controls (Speed, Volume, Transformations, Color Grading) based on the currently selected clip on the timeline.

Note: Legacy property panels (like old Text, Transitions, and Effects) were temporarily disabled from rendering to prevent regressions until they can be fully migrated to parse and write to the new TimelineData object structure. Export functionality remains compatible by extracting base features from the primary video layer.

…e UI

- Redesign `EditState` to `TimelineData` with multi-track support (`Track`, `Clip`) in `src/app/editor/types.ts`.
- Implement dynamic resizable UI panels using `ResizablePanelGroup` in `page.tsx`.
- Create a comprehensive `MultiTrackTimeline` with zoom, scroll, clip dragging, playhead tracking, and context menu actions (Split, Duplicate, Copy, Paste, Delete).
- Build a new `PreviewEngine` to concurrently render multiple layered video, audio, text, and sticker tracks.
- Implement an `AIToolsPanel` simulating System AI-configured features like Auto-Captions and Auto-Cut Silence.
- Add a `TrackPropertiesPanel` to adjust video transforms, speed, volume, and color filters dynamically on clip selection.
- Update export payload formatting to support the legacy single-clip FFmpeg renderer using properties derived from the new `TimelineData` structure.
- Removed legacy UI panels temporarily to ensure stability and avoid regressions with the new data state.
