Restructure as marketplace+plugin per Claude Code canonical layout

A Claude Code marketplace and plugin can live in the same repo, but
they're distinct entities: the marketplace is a catalog (`.claude-plugin/
marketplace.json` at the repo root) and each plugin lives at
`plugins/<name>/` with its own `.claude-plugin/plugin.json`.

Without this restructure, `/plugin marketplace add lua-ai-global/
claude-code-lua-plugin` failed with "Marketplace file not found at
.claude-plugin/marketplace.json" — the repo had a plugin manifest but
no marketplace catalog, so users couldn't install via Claude Code's
native marketplace flow.

Changes:
- Plugin contents moved to `plugins/lua-agent-builder/`
- New `.claude-plugin/marketplace.json` at the repo root references
  `./plugins/lua-agent-builder` per the documented relative-path
  source format (https://code.claude.com/docs/en/plugin-marketplaces#
  relative-paths)
- CI workflows updated with `defaults.run.working-directory:
  plugins/lua-agent-builder` so all jobs run from the plugin subdir.
  Tarball paths and check-coverage outputs adjusted.

Tested locally: `cd plugins/lua-agent-builder && npm install && npm
run lint && npm test` — 16 lints + 216 tests all green. MCP bundle at
plugins/lua-agent-builder/mcp/lua-platform/dist/server.js is 65 KB
(0.06 MB / 5 MB budget).

Install path now:
  /plugin marketplace add lua-ai-global/claude-code-lua-plugin
  /plugin install lua-agent-builder@claude-code-lua-plugin
  /reload-plugins
