refactor: move collectedInlineCss to AppRenderContext
Eliminates prop drilling of collectedInlineCss by adding it to ctx
(AppRenderContext). The CSS collector is now initialized once in the
ctx object and accessed via ctx.collectedInlineCss throughout the
render pipeline.
Changes:
- Add collectedInlineCss field to AppRenderContext type
- Initialize collectedInlineCss in ctx creation (single location)
- Remove separate variable declarations from renderToStream/prerenderToStream
- Remove collectedInlineCss parameter from getRSCPayload, createComponentTree,
getLayerAssets, renderCssResource, and createComponentStylesAndScripts
- Update ~30 call sites to use ctx.collectedInlineCss
