Ken Burns-style motion effects (zoom in/out, pan left/right/up/down) that
drag onto clips like regular effects. Instead of shader passes they
evaluate a per-frame transform offset in resolveVisualState, so they
stack with keyframed transforms and work in preview and export.
- intensity param (0-100%, keyframable) scales the whole effect
- easing select maps progress through the graph editor's bezier presets
- supportsStandalone: false hides them from effect-track creation
- empty shader pass groups are filtered out so pass-less effects and
zero-intensity blur no longer crash the compositor

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.
