Two new per-stack adapters on the #81 interface, dependency-free (anchor + #region markers,
same approach as tanstack — no AST parser, keeping dependencies:{}).

- Express: detect (express dep + an `= express()` site), scaffold the generic guard, and wire
  `app.use(patchstackMiddleware)` right after the app is created (import + region-marked insert,
  idempotent). verify() checks the guard is scaffolded + the middleware is wired.
- Next.js: detect (next dep); scaffold `middleware.ts` (+ co-located patchstack.rules.json) from a
  new template running the request-phase guard as edge middleware. An EXISTING middleware is never
  overwritten — we scaffold the rules and print a plan instead. verify() checks the managed
  middleware + rules are present.
- Registered in the orchestrator (tanstack → next → express → generic fallback); AGENT-INSTALL
  lists the newly auto-wired stacks.

+4 tests. 451 tests pass, typecheck + build clean.

* feat(protect): Express + Next.js adapters

* feat(protect): SvelteKit, Astro, Fastify adapters

Three more per-stack adapters (Arcjet-parity for the JS frameworks, minus NestJS/Python),
dependency-free — same anchor + #region approach, no AST parser, dependencies:{} unchanged.

- SvelteKit + Astro: seam-file-is-the-guard. New shared `seam.ts` (wireSeam/verifySeam) scaffolds
  the framework's server hook from a template (`src/hooks.server.ts` → handle, `src/middleware.ts`
  → onRequest) + co-located patchstack.rules.json. An EXISTING hook is never overwritten — scaffold
  rules + print a compose-with-sequence() plan instead.
- Fastify: register-into-app (like express). scaffoldGeneric now takes a guard-template arg so the
  Fastify plugin (builds a Request from the parsed fastify request → fetchGuard) lands as the guard;
  wire `app.register(patchstackFastify)` after the fastify() instance.
- Registered most-specific-first (tanstack → next → sveltekit → astro → fastify → express → generic).
- AGENT-INSTALL lists the newly auto-wired stacks.

+5 tests. 456 pass, typecheck + build clean.
