- Official Claude plugin marketplace submission prep — polished the generated Claude Code plugin metadata with repository, author URL, and discovery keywords, rewrote the copied plugin README so release artifacts no longer describe themselves as local-only scaffolds, and added an Anthropic marketplace submission packet covering source refs, runtime behavior, data handling, trust/safety notes, and validation commands. Tests now assert the generated plugin and marketplace artifacts keep this submission-ready metadata and avoid regressing to local-only wording. (nah-883)
