How barchart/common-js works

@barchart/common-js is a public, browser- and Node-compatible JavaScript utility library, not an application with one fixed end-to-end workflow. A consumer selects utilities for a task; the library supplies reusable language/date values, collections, predicates, serialization, messaging/models, command dispatch, HTTP/REST, and timing behavior. Groups reflect these runtime capabilities. Sampled source supports only the internal edges shown; other branches are retained from the README and file tree without assuming their wiring.
