* fix(relay): exit promptly on SIGTERM instead of waiting out docker's stop timeout On SIGTERM the relay drained sessions and called server.close(), which waits for every open socket. A TCP connection that never sends a byte (or sends partial headers) is not idle, and server.close() also stops the header-timeout checks, so nothing ever closed it. The process stayed alive until docker's --stop-timeout 300 SIGKILLed it: about five minutes of every cell VM replacement during a same-cap roll. Shutdown now tracks accepted sockets (including upgraded WebSockets), keeps the existing drain order, destroys sockets still open after a 5 s grace, waits (bounded) for queued pool clients, closes the database and exits 0. An unref'd 10 s backstop exits even if the database close hangs. SIGTERM/SIGINT use process.on behind a shutting-down guard so a repeated signal no longer kills the process with 143. The new blackbox test fails on the previous index.ts (silent TCP and partial-headers peers keep it alive past the test bound) and passes now. * style(relay): satisfy changed-lines lint gate in SIGTERM exit change
