Dogfood the Action + bump to v20.0.0 (Agentic Tooling) (#42)

- .github/workflows/pr-description.yml: uses our own Action (uses: ./action)
  to auto-write this repo's PR descriptions when a PR opens empty; skips
  quietly without ANTHROPIC_API_KEY and on forks. A living demo.
- Version -> 20.0.0 (Agentic Tooling): bundles the GitHub Action, generate
  command, and evals/leaderboard for npm. README badge + What's New (v19
  collapsed), CHANGELOG [Unreleased] -> [20.0.0], SECURITY table.

 A community-built library of professional skills for every field — product management, engineering, customer success, marketing, social media, writers, design, legal, finance, HR, sales, operations, research, and more. Each skill is a structured `SKILL.md` file that teaches an AI assistant how to produce professional-grade outputs for your workflows. Skills run natively in **Claude Code** and **Hermes Agent** (same open `SKILL.md` standard), and ship as ready-to-paste exports for **ChatGPT** and **Gemini** — see [Works With](#-works-with--cross-tool-compatibility).

-- **Personas** — 4 Claude Code output-styles (Startup CTO, Growth Marketer, Solo Founder, Product Leader) in [`output-styles/`](output-styles/).
+- **`generate` command** — `npx pm-claude-skills generate --from <url|file>` turns your docs into a standard-compliant `SKILL.md`.
-- **Orchestration guide** ([`ORCHESTRATION.md`](ORCHESTRATION.md)) — Skill Chain, Multi-Agent Handoff, Domain Deep-Dive, Solo Sprint.

-- **Static skill catalog** — a server-rendered, SEO-indexable catalog of every skill (linked from the README + Playground).
