Wrap the startup, waiting, assertions, and close-hook handling around the child
created by execa in a try block, and move the SIGKILL cleanup into finally while
preserving the existing graceful SIGTERM and close-marker behavior.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Wait for natural process closure before cleanup.
done() resolves when the synchronous fixture marker arrives. The finally block can then send SIGKILL before graceful shutdown completes. This test proves hook invocation, but it does not prove that shutdown awaits the hook.
Wait for the child close event with a rejecting timeout. Then assert the marker after closure. Make the fixture hook asynchronous if this test must prove that callHook("close") is awaited.

The bun preset delegates shutdown to srvx, which closes the server on SIGINT/SIGTERM without calling Nitro's runtime `close` hook. Cleanup handlers registered via the `close` hook were silently skipped in production. Wrap `server.close()` to run the `close` hooks after the server closes, mirroring the node preset fix in nitrojs#4522. `deno_server` has the same gap.

Resolves #4502
❓ Type of change
📚 Description
The
node_serverpreset no longer called Nitro's runtimeclosehook on SIGTERM or SIGINT, so cleanup handlers could be skipped in production. Nitro v2 usedsetupGracefulShutdown(listener, nitroApp)and ran the hook after connections drained; v3 delegates shutdown to srvx, which closes the server without calling Nitro hooks.This wraps
server.close()in the node server and cluster entries so the runtime hook runs once, is awaited, and still runs if the underlying close rejects. It runs after the server closes, matching the v2 order. Bun and Deno are unchanged because they did not call the hook in v2 either.The issue reproduction now works as expected: build the
node_serverfixture, start it, send SIGTERM, and the close-hook marker appears before shutdown completes.Verification
pnpm vitest run test/presets/node.test.ts: 66 passed with both rolldown and rollup.The hook shares srvx's normal shutdown budget. The fixture scheduler can keep the process alive after the server closes, so the test kills it after the assertion; that behavior already existed.
NITRO_SHUTDOWN_*remains out of scope.📝 Checklist
