preview popout
- New Lens category in the assets panel: Blur, Motion Blur, Zoom In/Out,
Pan x4, Shake, Pulse, Spin, Custom Zoom. EffectDefinition gains a
category field; tabs with an empty category are hidden, and the
properties-panel 'Open effects' button opens the first non-empty one.
- Motion effects work standalone: dropping them on the timeline creates
an effect-track element that animates (scale/translate/rotate) every
track below it, computed purely in the TS frame descriptor - no wasm
changes, identical in preview and export. supportsStandalone removed.
- Motion Blur: directional gaussian smear (amount + angle) reusing the
existing WGSL shader with arbitrary u_direction.
- Custom Zoom: start/end scale params (keyframable clip-level).
- MotionOffset gains optional rotate, accumulated clip-level and applied
to standalone layer quads via rotationDegrees.
- Rename clips (timeline context menu) and media assets (media panel
context menu) via a shared RenameDialog; asset rename persists through
storageService with rollback on error.
- Preview pops out into a Document Picture-in-Picture window and docks
back; button hidden where the API is unsupported.
- Export keeps running when the export popover is closed; only the
explicit Cancel button aborts.
- Captions and Adjustment tabs removed from the assets panel.

This implements the foundational architecture for video effects, starting with a multi-pass WebGL rendering pipeline and a customizable Gaussian Blur effect.
Key changes:
- WebGL Engine: Added `raw-loader` for `.glsl` shaders, multi-pass framebuffer rendering, and live offscreen canvas previews.
- Node Architecture: Replaced hardcoded background blur with `CompositeEffectNode` and added `EffectLayerNode` to apply effects to specific visual elements.
- Timeline & DND: Added a new `effect` track type. Upgraded drag-and-drop to support dropping effects directly onto the timeline. Consolidated track constants into a cleaner `TRACK_CONFIG`.
- UI/UX: Added an Effects tab in the assets panel with live previews. Added an Effect Properties panel with sliders and inputs for fine-tuning parameters.
- Data Model: Added `sourceDuration` to video and audio elements, and wrote a v8 storage migration to update existing projects to the new schema.
- Docs: Added `CHANGELOG.md` tracking v0.1.0 and v0.2.0, plus `docs/effects-renderer.md` to document the new WebGL pipeline.
