Nollup: Rollup-compatible Dev Bundler

Nollup is a Rollup-compatible bundler specifically engineered for rapid development workflows, currently at version 0.21.0. Unlike Rollup, which focuses on production-optimized bundles through aggressive tree-shaking and scope-hoisting, Nollup intentionally skips these optimizations to achieve exceptionally fast rebuild times. This makes it ideal for local development, enabling features like Hot Module Replacement (HMR) using existing `module.hot` conventions. It maintains compatibility with standard Rollup plugins and configuration files, allowing developers to leverage their existing Rollup ecosystem for application development. Nollup offers several modes of operation, including a CLI, Dev Server API, Dev Middleware API, and Compiler API, supporting frequent releases with a focus on developer experience.
