Summary

Complete user-visible rebranding from OrcaSlicer to Cosmos3D, covering the full application surface: build system, platform integration, GUI, GCode output, 3MF file format, CLI, and image assets.

What's changed

Build system & version identifiers: Project name, SLIC3R_APP_NAME/SLIC3R_APP_KEY, bundle identifier (com.cosmos3d.slicer), binary output name (cosmos3d), macOS icon and bundle name
Platform files: macOS Info.plist and MacOSXBundleInfo.plist (bundle ID, URL schemes), Windows .rc files, Linux .desktop entries (name, icon, exec, WMClass)
GUI strings: Dialog titles, error messages, URL scheme registrations, Windows registry entries, preferences labels across ~15 source files
IPC & instance checking: D-Bus interface names, macOS distributed notification names, Windows instance detection, URL scheme regex (backward-compatible with orcaslicer://)
Library: GCode producer writes "generated by Cosmos3D", 3MF parser detects both Cosmos3D- and OrcaSlicer- prefixes for backward compatibility, PrintConfig tooltips updated
CLI & process management: Error messages, binary name references in process spawning
Image assets: Full set of 20 Cosmos3D-branded images (PNG, SVG, ICO, ICNS) with all code references updated

Design decisions

User-visible only: Internal variable names (SLIC3R_*, ORCA_VERSION_*, SoftFever_VERSION) and source filenames (OrcaSlicer.cpp) are intentionally unchanged to minimize merge conflicts with upstream OrcaSlicer
Backward compatibility: URL scheme regex keeps orcaslicer alongside cosmos3d; 3MF parser reads both formats; GCode processor recognizes both generators
Attribution preserved: GitHub URLs to SoftFever/OrcaSlicer and BambuStudio credits are unchanged
No formatting changes: Pure string replacements only — no whitespace or style cleanup mixed in

What's NOT included

Gcodeviewer-specific icons (still use OrcaSlicer-gcodeviewer assets)
Localization file renames (.po/.mo files keep OrcaSlicer naming)
Auto-update URLs in AppConfig.cpp (still point to OrcaSlicer GitHub releases)
Internal enum values, CMake target names, thread names, ABI exports

Test plan

Build on macOS — verify binary is named cosmos3d, app bundle shows "Cosmos3D"
Launch and verify window title says "Cosmos3D"
Open About dialog — confirm text and images show Cosmos3D branding
Slice an object — check GCode header contains generated by Cosmos3D
Open an OrcaSlicer-generated .3mf file — should load correctly (backward compat)
Check Preferences → file/URL association labels say "Cosmos3D"
Verify cosmos3d:// URL scheme opens the app (macOS)
