Monitored services that send data after Connection: close (malformed HTTP)
were causing unhandled 'Parse Error' exceptions, crashing the process and
triggering a PM2 restart loop (191 restarts observed) which caused 502s.
Two-layer fix:
- monitorService.js: attach .on('error', noop) to the shared HTTP/HTTPS
keep-alive agents so socket-level parse errors don't escape as uncaught
exceptions
- index.js: process-level uncaughtException guard that swallows HTTP parse
errors (HPE_INVALID_CONSTANT / 'Parse Error') while still crashing on
real fatal errors
