```
io.github.libtmux.Server.Server.snapshot() -> ServerSnapshot
```

Captures the whole hierarchy in at most four listings, retrying once if the server is replaced.

<p>One server-wide listing per kind of object, so ordering and membership stay tmux's decision
rather than being re-derived from another listing's rows.

<p>Strict, unlike the lenient list accessors: a capture that failed raises instead of
returning an apparently valid empty graph, because a caller cannot tell those apart.

## Raises

- `LibTmuxException` — if a listing fails or the listings cannot form one valid snapshot
