bsb-js: BuckleScript Build Wrapper

bsb-js is a foundational JavaScript library designed to programmatically interface with the BuckleScript build system (`bsb`), which is crucial for compiling ReasonML and OCaml source code into JavaScript. As of version 1.1.7, it provides an API to trigger compilation tasks, allowing developers to integrate BuckleScript builds into various JavaScript tooling environments like Webpack (via `bs-loader`) or Rollup (via `rollup-plugin-bucklescript`). The library is currently active, receiving updates primarily for compatibility with new `bs-platform` versions and improving error resilience. Its release cadence is driven by maintenance and necessary adaptations to the BuckleScript ecosystem. A key differentiator is its role in decoupling the core compilation logic from specific bundler integrations, enabling a more modular and reusable approach to integrating ReasonML/OCaml builds within JavaScript projects.
