v0.3.0

Second release. The marketplace now hosts two plugins, and is itself a
well-made, CI-gated, community-complete public repo.

✨ New: github-keeper plugin

A new plugin to keep a public GitHub repo well-made and honest — two skills:

• /readme — audit and elevate a README. Rebuilds a thin/generic one into
  a polished, repo-specific README: an SVG banner, honest live badges, custom chips
  (a true fact linked to its proof), cognitive-funnel structure, a quickstart from
  real code. Preserves an existing voice; gates big rewrites on confirmation.
• /opensource — make a repo public-ready: community-health files (Code of
  Conduct, Contributing, Security, issue/PR templates), an honest CI gate, and
  the right repo settings. Never flips a repo public or changes settings without
  explicit confirmation; the CoC/security contact is the human's call.

Honesty gate throughout: never show a signal the repo can't back.

🛠 This repo, hardened

• High-quality README: clickable, honest, live badges; banner; TOC; GitHub
  callouts; "why this exists"; Quickstart.
• Open-source community health at 100%: Code of Conduct, Contributing,
  Security policy, issue/PR templates.
• CI: validate.yml runs deterministic checks (manifests, plugin structure,
  README links/H1/fences) on every push and PR.
• Private vulnerability reporting enabled; tidy merge settings.

📦 agentic-engineering — unchanged at 0.2.0

The spec-driven /pitch → /adr → /ship → /measure → /eval workflow with four
subagents and verification hooks.
