go-plugin

Audits and updates README.md and package-level Godoc in the go-plugin library to match the current exported API, field names, and behavioral contracts. Does not invent changes — only syncs what is verifiably out of date.

Reviews the go-plugin library's exported API for clarity, completeness, and developer experience — evaluated from the perspective of both host-program authors and plugin implementors. Reads only exported API (Godoc) and README/examples.

QA-focused review of go-plugin for correctness, fault tolerance, and concurrency safety — plugin subprocess lifecycle, handshake/reattach, mTLS, gRPC broker, and error propagation.
