feat(server): measure the Postgres driver null-socket crash on fatal errors

Browse Source

Add a process-level handler for uncaughtException and unhandledRejection.
It reports a fixed-cardinality verdict to first-party telemetry — whether
the crash matches the known postgres null-socket write defect — and calls
process.exit(1) on every path, so it does not change today's crash
behavior. This adds measurement only; it does not guard against the
defect.
