Adds `@clerk/nextjs/experimental/mosaic` (via `@clerk/react` and `@clerk/ui`) so the Mosaic UserButton can mount directly in a host app's tree, plus the matching `experimental/mosaic/styles.css`. The `@clerk/ui` mosaic entry is now a client boundary in whole (the bundle collapses the per-file directives) and is guarded against Emotion creeping back in, which meant replacing the UserButton trigger skeleton with StyleX.
The experimental subpath pointed at `src/mosaic/styles`, which is the StyleX build barrel: it pulls every migrated component into the graph so one stylesheet can be extracted. Publishing it made all of those components, and the headless primitive types behind them, part of the API. Give the export its own narrow entry instead. `@clerk/headless` is private, so leaving it external published a dependency that 404s on install. Bundling it broke differently: the declaration builder cannot follow the re-export chains in its emitted `dist/*.d.ts`. Correct the `tsconfig.mosaic.json` paths so it resolves to source (primitives live under `src/primitives`, so the old wildcard missed menu, popover, dialog and tabs and silently fell back to `dist`). StyleX moves to devDependencies and gets bundled: it compiles away at build time, so consumers should not inherit our version.
Keeps the experimental surface to the component and the props it takes; everything behind it stays internal.
Locks the props a consumer writes against `@clerk/nextjs/experimental/mosaic`: what the switcher modes are called, that a routing URL cannot ask for a modal, and that a menu row or profile page has to be one of its two shapes.
Floating UI arrives through the bundled @clerk/headless primitives, so leaving it external made it the one install this entry still demanded. SDKs inline this bundle so consumers need nothing beyond React and @clerk/shared.
…r trees Left external, the re-export resolved from the consumer's tree at runtime, which made @clerk/ui a dependency and installed its whole graph (Emotion, the Solana wallet adapters, ...) for every consumer, Mosaic or not.
The two tests guarding `mode` and `modePriority` against each other's wording go away with the divergence they guarded.
Pins the return shape: `{ name, slug? }`, `null` to decline, no arguments in.
The postcss plugin's package auto-discovery only recognizes a dependency as a
StyleX package when its manifest lists `@stylexjs/stylex` under dependencies,
peerDependencies, or optionalDependencies. Moving it to `@clerk/ui`'s
devDependencies silently dropped `packages/ui/src/mosaic` from extraction, so
no `:root { --cl-* }` token defaults were emitted and the preview deploy
rendered unstyled. Name the source in `include` instead of relying on discovery.

Description
Stacked on #9185
Adds an experimental subpath so Mosaic components mount directly in the host app's tree rather than being rendered by clerk-js.
UserButtonis the first one. It reads Clerk through hooks, so aClerkProviderabove it is all it needs:Checklist
