// Igneum wake: the apps' long-poll for a new jobs file (app/igneum-app/src/jobrun.rs, 0.3.6). Reached at /wake
// (public: the apps hold no token) and at /r/<token>/wake (the same function; the token matters only to POST).
// The contract and the whole handler live in ../lib/wake.mjs so the test can drive it without a database.
//   GET  wake?since=<stamp>[&hold=45]   up to 45 s; {stamp, at, added, changed, held_ms}; 30 a minute per IP
//   POST wake {stamp, added?}            the relay's auth (token in the path or x-relay-token, or the relay key in x-igneum-key;
//                                        the intake key opens nothing here, X23)
// maxDuration 60 s for this file is set in vercel.json.
