Operator identity for an LLM-backed flow.

```axon
persona Name {
  domain: ["ops", "telemetry"]
  tone: precise
  confidence_threshold: 0.85
}
```

A persona pins the prompt-engineering surface of a flow run: the
allowed knowledge domain, the tone preset, and the minimum
confidence the flow must clear before its output is accepted.
Personas are referenced by name from `run` statements via
`as PersonaName`.
