✅ No new issues found.

Reviewed changes — removes the clickable project/composition name affordances from the menu bar and replaces them with a dedicated InspectorOpenInEditor button.

• MenuBuildIndicator — drops the conditional project-name-as-link/git-link logic in favor of rendering InspectorOpenInEditor with a fixed folderLocation pointing at window.remotion_cwd. The project name is now plain text and always visible. Spinner layout is restructured into a cleaner mobile/desktop ternary.
• MenuCompositionName — strips all click-to-open-in-editor and click-to-show-in-file-manager behavior; the composition/asset name is now a non-interactive <span>, consistent with the PR intent to keep names non-interactive.
