OTP Process Abstractions with proc lib
summary
Shows how to build an OTP‑compliant process abstraction with proc_lib instead of wrapping gen_server, implements a small gen_lsp behavior (start_link, handle_request/notification/info) and a Credo language server that runs Credo, stores diagnostics in a cache (Agent), and publishes results to the editor. Demonstrates sys callbacks for debugging, supervision compatibility, and claims "a few lines of code" to wire it; demo reports ~482 Credo issues in Phoenix and the libraries exist as pre‑alpha working code.
