Track and associate traces with specific users

import { Laminar, observe } from '@lmnr-ai/lmnr';

// Option 1. directly pass userId to observe
await observe({
    name: 'processUserRequest',
    userId: 'user_123'
}, async () => {
    // Process user request here
});

// Option 2.Use Laminar.setTraceUserId
await observe({

}, async () => {
    Laminar.setTraceUserId('user_123');
    // Process user request here

# Note that this is static, i.e. you can't change this at runtime.

# Option 2: Use Laminar.set_trace_user_id
