Publish an event from a project flow.

```python theme={null}
prj.publish_event(name, payload=None)
```

Publish an event to trigger flows decorated with `@project_trigger`.

<GTable cols="12% 10% 78%">
  <GHead>
    <GRow>
      <GTH>Parameter</GTH>
      <GTH>Type</GTH>
      <GTH>Description</GTH>
    </GRow>
  </GHead>

  <GBody>
    <GRow>
      <GCell>`name`</GCell>
      <GCell>str</GCell>
      <GCell>Event name (must match the `event=` in a `@project_trigger`)</GCell>
    </GRow>

    <GRow>
      <GCell>`payload`</GCell>
      <GCell>dict</GCell>
      <GCell>JSON-serializable payload</GCell>
    </GRow>
  </GBody>
</GTable>

Events are namespaced as `prj.{project}.{branch}.{name}`, so events published on one branch only trigger flows deployed on the same branch.

```python theme={null}
self.prj.publish_event("model_trained", payload={"accuracy": 0.95})
```
