Rucksack Lite Resource Management Core

rucksack-lite is a JavaScript library providing the foundational `RucksackLite` class for managing and preparing JavaScript and CSS resources. It serves as the core resource abstraction layer, differentiating it from actual bundlers, and is utilized by the more comprehensive `rucksack` bundler package. Currently at version 6.0.0, the library underwent a complete rewrite in this major release, focusing on robust handling of both local and remote resources. It defines a `RucksackResource` class internally for managing resource paths, types (JS/CSS), and generating the necessary HTML markup for inclusion. While its release cadence appears somewhat irregular, major versions signify active development with significant architectural shifts, such as licensing updates and full rewrites. Its primary differentiation lies in offering a clean, object-oriented API for resource management, abstracting away complexities of path resolution and markup generation prior to the actual bundling process.
