The rendered guides and executable examples still taught the legacy
`ActorNursery.run_in_actor()` result-portal model even though #481
adds its blocking, linked-context replacement.
Deats,
- migrate one-shots to direct results through `to_actor.run()`
- preserve named target inputs with `functools.partial()`
- use daemon actors where reciprocal dialogs need longer lifetimes
- link the new API from core, asyncio and clustering references
- retain only explicit legacy/removal notes
