* feat(projects): add local icons and colors
* refactor(projects): simplify appearance handling
* fix(projects): serialize appearance saves
* test(app): update project appearance expectations
* test: fix project appearance CI expectations
* refactor(projects): organize appearance code
* fix(server): adopt main's reconcile model in project appearance updates
* fix(projects): preserve host-local appearance targets
* fix(desktop): restore Linux development startup
Ubuntu can block Electron's unprivileged user-namespace fallback while the npm-installed sandbox helper is not SUID. Disable the Chromium process sandbox only in the Linux development runner so packaged desktop policy remains unchanged.
* feat(projects): add custom project icons
Keep URL acquisition in the client so the host daemon only validates uploaded bytes. Project name and icon changes share one adaptive edit sheet.
* refactor(settings): scope projects by host
