```
matching/2
-spec matching({module(), term()}, t(Row)) ->
                  {ok, t(Row)} | {error, term()}
                  when Row :: tmux_model:row().
```

Prepare a trusted behaviour once, then apply its Boolean predicate.

Uses `c:tmux_matcher:prepare/2`; preparation failure returns {error, Detail}.
Exceptions in either callback propagate. A matcher requires a captured
snapshot; a `from_list/2` selection returns matcher_requires_snapshot. The
application chooses Module.

## Parameters

- `Argument1` (`{module(), term()}`)
- `Selection` (`t(Row)`)
