nojson

Work with the nojson Rust crate: parse and generate JSON via the `Json<T>` wrapper, `RawJson`/`RawJsonOwned`/`RawJsonValue` for low-level access, the `DisplayJson` trait, and in-place builders `json()` / `object()` / `array()`. Implement `DisplayJson` + `TryFrom<RawJsonValue<'_, '_>>` to round-trip custom types; navigate objects with `to_member` / `to_path_member` and `required()` / `optional()`; produce rich error context via `RawJsonValue::invalid()` and `JsonParseError::get_line_and_column_numbers`; handle JSONC with `parse_jsonc`. Use when the task mentions nojson, its no-macro/no-dependency JSON API, or no_std JSON work with this crate.
