Parse .srt files into chunks and insert them as text elements on a new text track using the existing caption styling defaults. Displays a warning when malformed cues are skipped during import.
* Batch caption text insertion

Batch caption insertion in a BatchCommand so that undo will batch undo all subtitle insertion from either srt file or ai transcriptions.
* Move subtitle parsing into a shared interface

Extracted the srt specific extraction behind a generic shared interface to allow easier adding of other subtitle formats in the future.
* Apply better default styling for subtitles.

Shrink font size, aim to layout 5% above bottom, keep subtitle width 80% of video, wrap text on new lines if too long.
* Update Captions Panel UI
Split captions panel into Generate and Import tabs as they are two different approaches for adding captions.
* Add biome formatting fixes
* Add .ass subtitle import support
Extend subtitle import to accept .ass files alongside .srt, map supported .ass styles onto imported text elements, and display warnings when unsupported .ass features are skipped.
* Change “Import subtitles” button style
* refactor: review fixes
* fix: convert subtitle times from seconds to ticks
* refactor: replace captions tab switcher with import action button

Fix for #703.
Adds an optional sampleRate parameter to the decodeAudioToFloat32() function. The caption transcriber passes in a value of 16000 to prepare audio in the format Whisper expects.
Major features and improvements:
* **Clip Effects**:
* Added UI in Properties Panel to manage effects on video/image clips (add, remove, toggle, reorder).
* Implemented dynamic parameter fields for effects.
* Added support for keyframing effect parameters.
* **Assets Panel**:
* Added sorting options: Name, Type, Duration, and File Size.
* Persisted view preferences (grid/list mode, sort order) to local storage.
* Refactored media item rendering and drag interactions.
* **Timeline & Interaction**:
* **Keyframe Dragging**: Added ability to drag keyframes directly on the timeline element.
* **Resizing**: Improved resize logic to respect neighboring clips (prevents overlaps).
* **Visuals**: Implemented tiled background rendering for video/image clips on the timeline.
* **Shortcuts**: Added "Deselect All" action bound to the `Escape` key.
* **Fixes**: Corrected drag-and-drop coordinate calculations when the timeline track area is scrolled.
* **Text Elements**:
* Refactored text background storage to use an explicit `enabled` flag.
* Added `V8toV9` storage migration to update existing projects.
* **Architecture**:
* Moved export state management to `ProjectManager` for better lifecycle handling.
* Refactored `PropertiesPanel` sections to be more composable (custom headers, borders).
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.
