* fix: validate request origin in dev server before Vite serves content The dev server origin check middleware was registered after Vite's built-in file-serving middleware, so requests to internal paths (/@*, /__vite*, /node_modules*) were served before any validation. - Register origin check directly in configureServer body (pre-middleware) so it runs before Vite serves source files or internal endpoints - Restrict CORS origin to localhost variants (127.0.0.1, [::1], *.localhost) - Add Sec-Fetch-Site: cross-site check as defense-in-depth - Block image endpoint redirects to internal Vite paths (/@*, /__vite*, /node_modules*) - Add regression tests for both App Router and Pages Router dev servers * refactor: use shared validateDevRequest() in pre-Vite middleware Address review feedback: - Replace inline origin-check logic with validateDevRequest() call to maintain a single source of truth (includes x-forwarded-host, allowedDevOrigins, and *.localhost support) - Fix misleading Sec-Fetch-Site test in app-router.test.ts: use node:http instead of fetch() which strips Sec-Fetch-* forbidden headers - Add defense-in-depth comment on the redundant Pages Router check
