Four examples look up one SKU in `stock.json`: `connect/stock-api`,
`connect/http-client`, `contracts/openapi-server` and `ai/mcp-server`. They did
it with a JsonPath filter, `$[?(@.sku == '${header.sku}')]` with `resultType:
java.util.List`, then checked the size and took `${body[0]}`.
They now unmarshal the file and find the item with one line of Groovy:
```yaml
- unmarshal:
json:
library: Jackson
- setBody:
expression:
groovy:
expression: "body.find { it.sku == headers.sku }"
```
That gives the item as a map, or null, so the choice checks `${body} ==
null` and the `${body[0]}` step goes. Groovy reads more plainly than the filter
syntax, and models write it well. In local-model benchmark runs the model
repeatedly dropped the size-check-and-unwrap step after the JsonPath filter.
READMEs, the `teaches` metadata and `camel-jbang-example-catalog.json`
(regenerated) are updated to match. `transform/json-transform` keeps JsonPath
because it teaches jsonpath and jq. The connect-service examples only read
single fields (`$.orderId`) and are unchanged.
Tested:
- `camel test run` passes for all four examples on 4.23.0-SNAPSHOT
- `connect/stock-api` on `--camel-version=4.22.1`: `curl /stock/CAMEL-MUG`
returns 200 with the item, `/stock/CAMEL-SOCKS` returns 404 with `unknown sku
CAMEL-SOCKS`
