JSX Plus Build Plugin

build-plugin-jsx-plus is an early-stage build plugin, currently at version 0.1.4, designed to enable and transform custom `jsx-plus` syntax within the `ice.js` framework ecosystem. It provided a dedicated transformation layer for this specific JSX dialect. Given its low version number and the current iteration of the framework, `@ice/app`, being in its 3.x series with actively maintained plugins at much higher versions, this specific package is considered abandoned. Its original functionality may have been absorbed directly into newer `@ice/app` versions, replaced by standard JSX tooling, or deprecated in favor of more conventional approaches. It had a sporadic release cadence, which has effectively ceased for this package. Key differentiators included its support for `jsx-plus` specific syntax features, distinguishing it from standard React JSX transformers.
