v2.0.0

Major Changes

• 8a165eb: Rewrites internal architecture to align with @testing-library/svelte:
  • discrete modules for cleanup, mounting, setup, and props replace the old core / directory
  • Drop all Svelte 3/4 legacy code paths; Svelte 5 only
  • Use Proxy-based shallow reactive props ($state.raw) instead of $state with Object.assign
  • Task-based cleanup system with addCleanupTask/removeCleanupTask replaces the dual-Set (targetCache/componentCache) approach
  • advance() now returns { frameInvalidated: boolean } for testing on-demand and manual render mode invalidation logic
  • Container accepts contextOptions via renderOptions.context for passing
  • Canvas-level props like colorSpace, toneMapping, shadows, and dpr
  • Container uses a properly sized DOM element so getBoundingClientRect() returns real dimensions, fixing default camera aspect ratio
  • Vite plugin skips adding auto-cleanup setup files when test.globals is enabled
