```
FilterLookup.parse(_:as:model:)(lookup: String, as: Root.Type, model: String) -> FilterExpr<Root>
```

Builds an expression from one `field__operator=value` lookup.

The model name selects the vocabulary: `"pane"`, `"session"`, and so on.
A field can be named by wire id, Swift property, or tmux format name —
whatever the schema lists as an alias.

## Raises

- `FilterLookupError`
