clipmem 0.2.13

//! Parity test for the clipmem agent-skill packages.
//!
//! Asserts that the canonical skill under
//! `skills/clipboard-memory/`, `extras/openclaw/clipboard-memory/`, and the
//! portable mirror under `extras/agent-skills/clipboard-memory/` stay in sync
//! on everything that matters to a calling agent: frontmatter, documented CLI
//! surface, reference files, and the setup-check script.
//!
//! Some files are expected to be byte-identical across variants (the
//! "shared reference core"); others are allowed to diverge on metadata only
//! (SKILL.md, troubleshooting.md).
