GHSA-7xp7-m392-h92c: @evomap/evolver has an unbounded request body in proxy /asset/submit that causes persistent disk-exhaustion DoS

The EvoMap proxy daemon’s HTTP body parser accepts requests of any size, and the POST /asset/submit route persists the full request body — verbatim and uncapped — as a JSONL line in <dataDir>/messages.jsonl. An unauthenticated local attacker (other local user, container neighbor, or malicious npm postinstall script running on the same host) can repeatedly POST large bodies to fill the disk. On restart, the daemon synchronously reads the entire file via fs.readFileSync, making the OOM/crash persistent.
