v1.3.0

Added

• copy-audit skill — audit product copy, UI microcopy, and (with --mode=comments)
  code-comment slop and test-runner names across a git repo or diff. AST-based extraction
  (tree-sitter for 40+ languages plus babel/Astro/remark/yaml) reaches markdown prose,
  headings, and alt-text, JSON/YAML copy values, and UI microcopy in HTML/Astro/Svelte/Vue/
  JSX/TSX; parallel subagents judge each unit with full-file context against four cited
  content pillars (plain language, inclusive, UX microcopy, voice/grammar) or, in comment
  mode, comment-quality plus Rule 9. Verdicts are keep/rewrite/flag/delete and every rewrite
  is a SHA-guarded char-offset splice that changes text but never code structure, with a
  verify phase asserting zero code-line changes. Read-only until you approve the rewrites.
  Subsumes the standalone comment-audit skill. Runs against a git repo/diff, against pasted
  text or a standalone file with no git (--input / --stdin --as, verified by exact
  pre-image reconstruction), and against PDFs (text pulled with Node's built-in zlib and
  reviewed read-only — never spliced back into the binary).
• Marketing site: a fourth skill card, a copy-audit mockup, FAQ entries, and an Operator's
  Playbook PDF for copy-audit.

Changed

• The plugin now bundles four skills; the plugin and marketplace manifests, the READMEs, and
  the marketing site update from "three" to "four".
