// Module-level pg-boss singleton. server.ts initializes the boss + starts
// Process-level pg-boss singleton. server.ts initializes the boss + starts
// the worker; feature code (e.g., activities.server.ts) calls `getBoss()`
// to enqueue jobs against the same instance. The singleton's lifecycle
// is bound to the Node process — startWorker calls boss.start(); the
// SIGTERM handler stops it.
//
// The instance lives on globalThis, NOT in a module-local variable. In
// production there are TWO copies of this module in the process:
// server.ts imports the TypeScript source directly (node
// --experimental-strip-types), while route handlers live in the
// bundled build/server/index.js with its own module instance. A
// module-local `_boss` set by server.ts is invisible to the bundle, so
// every request-path enqueue (notifications fan-out, federation
// deliveries, komoot imports) silently failed in production with
// "pg-boss not initialized". Symbol.for() gives both copies the same
// global registry key.
