3D Model Import Improvements

Import button favors 3MF with embedded feature history and falls back to geometry-only files when needed. BREP JSON remains supported for history-only import.
Import 3D Model feature auto-detects STL versus 3MF from strings, data URLs, or ArrayBuffers. 3MFs merge to a single editable mesh; STLs import as geometry only.
File Manager save and load now use compact 3MF with embedded feature history and a thumbnail. Legacy JSON stays compatible for older saves.

"Edit Image" opens an in-app paint-style editor. If no image is set, it starts with a 300 x 300 white canvas.
Editor UI prefers dark mode, renders at true 1:1 pixels with device pixel ratio awareness, and appears immediately on open.
Resize handle on the bottom-right expands or crops the canvas while preserving edits.
Brush improvements include live cursor outline, multiple shapes (round, square, diamond), and an eraser that respects the selected shape.
Paint Bucket tool with tolerance slider (0-255) fills contiguous regions based on the composited image and applies paint only to the draw layer.
Finish saves the edits back to the feature and triggers a recompute; Cancel discards edits.

New GitHub storage backend lets you save models and settings directly into a repository.
Storage writes real .3mf files plus a small .meta.json sidecar in brep-storage/__BREP_DATA__/.
Configure it in Display Settings → Storage (GitHub) using a fine‑grained PAT with Contents read/write.
