Agent Skills: meaningfy-code-review

The Meaningfy pre-PR review — two modes (standalone = five lens subagents fanned out in parallel, one lens each; interactive main-thread), a methodical catalogue-complete review procedure (traverse the whole `cosmic-python` region a lens owns, not a fixed subset), and a fit-and-refactoring investigation, reported by priority. Use to supply the review criteria, modes, and dispatch contract for a Meaningfy change. Trigger on "Meaningfy review checklist", "architecture-conformance review", "review against cosmic-python layers", "pre-PR review criteria", "review modes", "review lenses". For the read-only standalone run, use the external `code-review` command or the `code-reviewer` wrapper.
