```
with_owned(Options, Function)
-spec with_owned(owned_options(), fun((t()) -> Value)) ->
                    {ok, Value} |
                    {error, scope_failure() | map()}.
```

Start an owned daemon, run a callback in the calling process, then stop it. Performs `start_owned/1` and token-based `stop_owned/1` around the callback. With successful cleanup, returns {ok, Value} or re-raises the original callback exception. A returned error tuple is an ordinary callback value. Startup failure passes through without invoking the callback.

Cleanup failure returns `t:scope_failure/0`, including both server and ownership
handles for inspection and an explicit stop retry. It preserves the callback
outcome and cleanup evidence separately; it never claims timeout is retirement.
See `with_server/2` for callback and separately allocated resource obligations.

## Parameters

- `Options` (`owned_options()`)
- `Function` (`fun((t()) -> Value)`)
