query.FilterExpr.or(self, other: Self) -> Self

Combine two expressions with ordered short-circuiting disjunction.

Adjacent disjunction nodes are flattened without reordering operands.

## Example

```rust
use libtmux::query::BoolField;
use libtmux::query::__private;

struct Row;
let field: BoolField<Row> = __private::bool_field("row", "done");
let expression = field.eq(false).or(field.eq(true));
assert_ne!(expression, field.eq(true).or(field.eq(false)));
```
