AI-powered tooling: GitHub Action, generate command, evals + leaderboard (#41)

Three features riding 2026 trends (agentic CI, codegen, evals), sharing one
dependency-free Anthropic client (bin/lib/anthropic.mjs).

1. GitHub Action (action/) — run any skill in a consumer repo's CI:
   uses: mohitagw15856/pm-claude-skills/action@main. Composite action +
   run.mjs (loads the bundled SKILL.md, calls the API, exposes result as a
   step output / file). Docs with auto-PR-description example.

2. generate command — `npx pm-claude-skills generate --from <url|file>` turns
   a team's docs into a SKILL.md following the authoring standard
   (bin/generate.mjs, wired into the CLI; needs ANTHROPIC_API_KEY).

3. Skill evals + Leaderboard — evals/run-evals.mjs runs each case across models
   and scores output with an LLM judge (structure/completeness/usefulness/
   grounding); scripts/build-leaderboard.mjs renders web/leaderboard.html
   (built in the Pages deploy, falls back to clearly-labelled example data).
   Linked from README, catalog, and playground.

Offline-testable parts verified (prompt building, skill loading, graceful
errors, leaderboard render). SkillCheck/audit/exports all green.
