lbundle: Zero-Configuration Library Bundler

lbundle is a small, zero-configuration bundler specifically designed for NPM libraries, leveraging Rollup.js for bundling and SWC (written in Rust) for fast transpilation. Its core philosophy is to minimize setup by heavily relying on best practices defined within the `package.json` file, using fields like `source`, `main`, `module`, `types`, `unpkg`, and `exports` to determine build inputs and outputs. The current stable version is 1.6.0, with frequent minor releases focusing on bug fixes and feature enhancements, as evidenced by its recent changelog. It differentiates itself by its 'convention over configuration' approach, automatic asset optimization, and robust TypeScript support, making it an ideal choice for library authors seeking a streamlined build process without extensive build toolchain configuration.
