ScreenTinker 78a4ee4d37 fix(server): last-resort uncaughtException/unhandledRejection safety net (#114)
A FK constraint violation crashed the whole process on 1.9.1-beta2 with a
bare "FOREIGN KEY constraint failed" and NO stack — so it couldn't be root-
caused. better-sqlite3 is synchronous, so such a throw inside a socket.io
handler (no local try/catch) propagates to uncaughtException, and with no
handler Node exits traceless.

Add a small top-of-server.js net that logs the FULL err.stack (file:line of
the offending write) + timestamp, best-effort closes the DB (WAL flush), then
exits(1) so systemd restarts fresh. NOT catch-and-continue — after an uncaught
throw the process state is undefined, so we never keep serving. This is the
investigation tool the root-cause fix is blocked on, plus the fleet-wide-crash
net #114 asked for.

Verified (not assumed):
- A synthetic synchronous FK throw inside a real socket.io handler IS caught by
  uncaughtException, logs the full stack incl. the throwing file:line, exits 1.
- Non-over-reach: a FK throw in an Express route -> Express handles it (500), a
  throw in a local try/catch -> caught (200); the global net does NOT fire and
  the process stays alive. Last resort, not a catch-all.
- 149 server tests green; server boots clean (net doesn't trip on startup).

The root-cause FK fix is SEPARATE and waits on the stack trace this produces.
