Deploy Studio to /_studio path in Vercel deployments

[Claude]

Studio SPA was being served from the root path in Vercel deployments. Now serves from /_studio to separate it from API routes and future root-level content.

Changes

Build script (apps/server/scripts/build-vercel.sh):

• Copy studio dist to public/_studio/ instead of public/

Vercel configuration (apps/server/vercel.json):

• Add VERCEL: "true" to build env
• Update asset cache headers: /_studio/assets/* instead of /assets/*
• Add rewrites for /_studio and /_studio/* to serve Studio SPA

Vite configuration (apps/studio/vite.config.ts):

• Set base: '/_studio/' when VERCEL env var is present
• Ensures all asset references use correct path prefix

Result

• Studio accessible at https://domain.vercel.app/_studio
• API routes remain at https://domain.vercel.app/api/*
• Non-Vercel deployments unaffected (use relative paths)

• Update Studio build base path on Vercel to /_studio/ via Vite config.
• Copy Studio dist/ output into apps/server/public/_studio/ during Vercel build.
• Update vercel.json headers/env and add /_studio routing rules.

File	Description
apps/studio/vite.config.ts	Sets Vite base to /_studio/ when building on Vercel so asset URLs resolve correctly.
apps/server/vercel.json	Adds build env var and updates headers/redirects/rewrites intended to serve the Studio SPA under /_studio.
apps/server/scripts/build-vercel.sh	Copies Studio build output into public/_studio/ for Vercel static hosting.

The current rewrite rules don’t provide an SPA fallback for deep Studio routes (e.g. /_studio/settings). /_studio/(.*) -> /_studio/$1 is effectively a no-op and will 404 when the file doesn’t exist. Update rewrites to route all non-asset /_studio/:path* requests to /_studio/index.html (while leaving /_studio/assets/* to serve static files).

Suggested change

	{ "source": "/_studio/(.*)", "destination": "/_studio/$1" },
	{ "source": "/_studio/assets/:path*", "destination": "/_studio/assets/:path*" },
	{ "source": "/_studio/:path*", "destination": "/_studio/index.html" },

The PR description mentions separating Studio from “future root-level content”, but this redirect forces / to always go to /_studio, which would block serving anything else at the root later. Consider removing this redirect (or making it conditional/temporary) so / remains available.
