/**
 * Mirror generated provider command files (e.g. OpenCode's
 * commands/impeccable.md) from dist/ into the tracked root harness folders.
 * Without this, the release sync ships skills/agents/hooks but no slash
 * command bridge, so direct GitHub, npx-skills, and submodule installs of
 * OpenCode stay bridge-less (#483). Per-entry copy like the skills sync:
 * the destination directory is never removed, so repo-local or pinned
 * command files are preserved.
