Typed JSON values and checked application decoders for Pooka.

```sh
pooka add pooka_json
```

```pooka
import pooka/json/decode

let count = decode.field("count", decode.int())
assert decode.read("{\"count\":3}", count) == Ok(3)
```

Parsing uses Erlang’s native JSON parser. Objects preserve order and duplicate keys; field lookup uses the first occurrence. `pooka/json/decode` checks the typed JSON tree and reports field paths. Use bounded decoding for untrusted input.

See the [API documentation](https://pooka-json.hexdocs.pm/) for the rest.
