CAMEL-25763: the route rung shows the content-based router, the splitter,
the aggregator, the filter and the multicast. This adds three EIPs users need
often, which no example shows yet: the idempotent consumer, the content
enricher (`pollEnrich`) and the wire tap.
## What
- **`route/enrich-and-dedupe`**, with the web shop orders plus
`resent-order-1001.json` (ORD-1001 sent twice) and `customers/` (name and tier
per customer):
- **`idempotentConsumer`** with an in-memory repository (a `beans` entry)
accepts each order id once. With `skipDuplicate: false`, the resent order is
logged as a duplicate instead of being dropped silently.
- **`pollEnrich`** reads the customer's file with `variableReceive:
customer`, so the order stays the body. `unmarshal` with `variableSend` and
`variableReceive` parses the variable in place.
- **`wireTap`** sends a copy to an `audit` route that writes
`audit/<orderId>.json`. `audit/` is declared as data (`camel.jbang.dataDir`).
- **README** with the usual sections, and a **Citrus YAML test** in the CI
matrix. It is fifth in the route group. The catalog and the README tables are
regenerated.
## A pitfall the example works around
The file name for `pollEnrich` is computed into a header first. With
`file:customers?fileName=${body[customer]}.json`, the poll fails with `Key:
customer not found in bean: .../customers/C-482.json of type: java.io.File`.
The reason is the file component's poll optimization (CAMEL-21733): it hands
the `fileName` expression to the file consumer, which evaluates it against the
polled file, and so sees the message's headers but not its body.
`allowOptimisedComponents: false` also works. I'll raise it separately for
Camel.
## Checks
- `camel validate yaml --canonical` reports nothing.
- The routes run on the released Camel 4.23.0 and log what the README shows.
A `camel run --dev` reload accepts the orders again, because the repository
bean is recreated.
- The Citrus test passes (TEST SUCCESS).
