Protocols for pluggable skill sources and invocation policies.

Core SDK stays protocol-driven (see AGENTS.md §4.1). These protocols let
wrappers or paid tiers plug in alternative skill storage (HTTP registry,
plugin bundle, enterprise policy) without touching the core.

## Import

```python theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
from praisonaiagents.skills import protocols
```
