Monaco-editor and @monaco-editor/react were imported eagerly from
main.tsx so that the locally-bundled Monaco was registered with
@monaco-editor/react (CSP blocks the default CDN load). This pulled
the ~3 MB monaco chunk into every cold app start regardless of
whether a user ever opened the editor.
Move the Monaco setup into a new frontend/src/lib/monacoLoader.tsx
module that exports React.lazy-wrapped Editor and DiffEditor
components. The lazy factory awaits a one-shot setupMonaco() that
dynamic-imports monaco-editor, @monaco-editor/react, and the editor
worker, then calls loader.config({ monaco }) and sets
window.MonacoEnvironment before resolving the underlying component.
Concurrent first mounts share a single setup promise so the work
runs at most once per process. The three consumers (EditorLayout,
FileViewer, GitSourceDiffDialog) wrap their editor in <Suspense>
with a transparent fallback that preserves layout while the chunk
loads.
main.tsx loses three eager imports plus the MonacoEnvironment +
loader.config bootstrap. The vite.config.ts manualChunks group from
PR #823 was already prepared for this; the monaco chunk now loads
on demand instead of being bundled into the entry chunk.
