skill/scripts keeps command-metadata.json and the page JS; every .mjs entry point, lib/, and live/ are gone (the binary owns those verbs). Adds the POSIX launcher, impeccable.cmd, VERSION (copied from the new root ENGINE_VERSION), scripts/fetch-engine.mjs (bun run fetch:engine) to pull the pinned binary into skill/scripts/bin/<os>-<arch>/, and gitignores that bin dir. Prepared with AI assistance (Claude Code).
