FullSpectrum Studio v0.4.9 Official Release

FullSpectrum Studio v0.4.9 Official Release

This release is the first official package after the v0.4.8 community
reliability preview. It keeps the same honest scope: FullSpectrum reduces and
remaps existing Bambu painted .3mf states. It does not repaint, smooth or
clean up a badly painted model.

What changed

• Smart quality is now the recommended default. It tests practical, balanced,
  detail and high-detail plans, scores the final validated palette, and keeps
  the best tradeoff for the painted usage in that model.
• Physical anchor selection now favors filament choices that produce better
  final Bambu-reconstructed mixed swatches, not just closer direct colors.
• macOS and Windows both expose a catalog-region selector for Bambu planning
  colors. The chosen region is written into warnings, JSON output and the
  shareable report.
• Catalog regions are planning metadata only. FullSpectrum does not query live
  Bambu store stock, so check availability before buying filament.
• The v0.4.8 fixes remain in place: real error reports, local debug logs,
  cancellable conversion, progress heartbeat text, readable dark-mode controls
  and safer large-model preview handling.

Compatibility

• Primary input remains a painted Bambu .3mf.
• Textured OBJ/GLB import remains experimental and size/format constrained.
• Very complex or noisy painted files can still be slow or visually imperfect,
  because the output can only be as clean as the original paint-state data.
• Every generated .3mf is reopened and validated before the app offers it to
  Bambu Studio or OrcaSlicer.

Validation used for this release

• python3 -m unittest discover -s tests -v
• swift build
• ./script/build_and_run.sh build
• Local conversion checks for catalog-region output, smart Bambu Core planning
  and CMYKW quality-100 planning on the public bald-eagle test model used
  during the v0.4.8 reliability pass.
