0.2.0

Added

• Edit mode: move and scale top-level nodes of glTF/GLB models via a gizmo
  (Edit model in the hover toolbar or the 3D-view sidebar) or precise number
  fields in the sidebar. Rotation is deliberately not offered.
• Edits are saved to a <name>.edit.gltf/.edit.glb next to the file — the
  original is never modified. Re-entering edit mode re-applies saved edits by node
  name onto the fresh original, so edits survive file regeneration.
• New setting Locked node prefixes (default env__): nodes whose names match a
  prefix cannot be selected or edited.
• Edit mode works in all three viewing paths (code block, embed, file view — the
  latter two are operated via the sidebar) and pauses auto-rotate while active.
• The file view now reloads when its file changes on disk and follows theme changes.

Fixed

• The Auto-rotate setting now applies to already-open viewports immediately
  instead of only after a reload.
• Reloading a model (file regeneration) no longer leaks a WebGL context per reload.
• Discarding edits while the model reloads in the background now shows a notice
  instead of silently doing nothing.
