2.0.0: Wavemaker for every agent host

• One repository for every host (renamed from wavemaker-cursor-plugin): Agent Plugins root
  manifest with OpenAI listing metadata (Codex, ChatGPT, Cursor, Kiro, Grok Build), Cursor and
  Grok Bot, Claude Code plugin and adwave marketplace, Codex repo marketplace, Gemini CLI
  extension, and server.json for the official MCP Registry (io.wavemaker/wavemaker).
• The skill now covers the twelve current tools (search, read, write, generate, edit,
  compose, watch, listen, compare, review, deliver, run), prices work before
  spending, follows jobs without resubmitting, and tells the agent when to use Wavemaker.
• Current Wavemaker icon; homepage https://wavemaker.io.
• scripts/validate.mjs checks every manifest; CI runs it with the Claude and registry validators.
