// #7003 — the RED/GREEN spec in main-server-keepalive-timeout-7003.test.ts proves
// getMainServerTimeoutConfig() raises keepAliveTimeout/headersTimeout above Node's
// unconfigured 5_000ms default, and that the original fix wired it into
// scripts/dev/run-next.mjs. But run-next.mjs only runs `npm run dev`/`npm start`
// from a source checkout. The server real end users run — `omniroute serve`
// (npm-installed CLI), Docker, and Electron — spawns the standalone Next build's
// server.js via scripts/dev/run-standalone.mjs, which prefers server-ws.mjs
// (built from scripts/dev/standalone-server-ws.mjs, copied byte-for-byte into
// dist/server-ws.mjs by scripts/build/assembleStandalone.mjs) over the bare
// server.js specifically because it wraps `http.createServer` with production
// behavior the bare server lacks (peer-IP stamping, method/HEAD guards, WS
// proxying, TLS). Before this fix, that wrapper left Node's http.Server
// keepAliveTimeout/headersTimeout at their unconfigured defaults, so the
// JetBrains AI Assistant reconnect bug reproduced by main-server-keepalive-timeout
// -7003.test.ts still hit the production entry point every real user runs.
//
// standalone-server-ws.mjs has top-level side effects (monkeypatches
// http.createServer, generates a random UUID, and unconditionally
// `await import("./server.js")` — a file that only exists in the assembled
// standalone output, not in the source tree) so it cannot be imported
// in-process. Guard the fix by inspecting the source, mirroring the pattern
// used for run-next.mjs in run-next-node-env.test.ts.
