filter syntax for node search box

### Feature Idea

Please add syntax for the "node filter condition" in the node search box which allows to write something like

```input:STRING output:INT source:was*```

instead of clicking through the node filter condition mask.

### Existing Solutions




### Other

also the words `input` `output` `category` and `source` all start with a unique letter, so it's should be possible to write anything from `input:` `inpu:` `inp:` `in:` `i:`

Start by locating the node search box and its existing node filter condition mask in the frontend. Implement the requested input, output, category, and source syntax, including unique-prefix forms and the shown wildcard example, then verify that typed conditions produce the same filtering behavior as the mask.
