Major Feature Release

This is a substantial release that significantly expands DefinedMotion's capabilities, particularly for mathematical animations.

⚡ New Features

New SVG rendering engine - Now using SVG as a general intermediate format for vector shapes.
LaTeX support - Full LaTeX → SVG → 3D pipeline for rendering mathematical expressions as true 3D geometry
LaTeX query system - Spatial querying API to get positions and bounds of LaTeX substrings, enabling precise highlighting, marking, and color manipulation of expression parts using \dmClass{tag}{content}
LaTeX animations - Pre-built animation helpers including:
- latexWriteAnim - Reveal formulas with writing effects
- latexHighlightAnim - Color pulse animations on tagged parts
- latexMarkAnim - Pulsating bracket overlays
- latexParticleTransitionAnim - Particle-based formula morphing from one expression to another

Updated camera movement toolkit - More intuitive camera animation system that uses the deferred animations released in v0.2.0.
HDRI performance increase - HDRIs are now much more performant. Instead of calculating the blur over and over again, it's calculated once and reused.
Resize handling - Fixed viewport resizing issues when opening the browser inspector.

Enhanced audio support - More robust audio handling. Will seek in already fired audio. Handles scrubbing correctly. Solves many small problems.
FFmpeg rendering fix - Resolved audio rendering bug for the tutorial_easy3 example

Many new examples and tests - DefinedMotion now has 12 examples and 34 tests to look at.
Significant README update - New README sections covering many details including the internals of DM.
