JsonUnit diff attachment integration for Allure Java.

io.qameta.allure:allure-jsonunit

dependencies {
    testImplementation(platform("io.qameta.allure:allure-bom:<allure-version>"))
    testImplementation("io.qameta.allure:allure-jsonunit")
}

Use JsonPatchMatcher.jsonEquals(...) when comparing JSON payloads.

assertThat(actualJson, JsonPatchMatcher.jsonEquals(expectedJson));

• JsonUnit comparison differences.
• A rendered JSON diff attachment named JSON difference.

This module still uses module-local HTML rendering for JSON diffs. It is intentionally separate from the HTTP exchange attachment model.
