/**
 * @fileoverview Static guard for the Claude Code plugin the repo publishes about itself.
 *
 * `.claude-plugin/marketplace.json` at the repo root makes `/plugin marketplace add
 * Ark0N/Codeman` work, and the one plugin it lists is the repo itself (`source: "./"`),
 * so the plugin's component roots ARE the repo root. Two things follow and both are
 * pinned here: the manifests must carry package.json's version (Claude Code's
 * `plugin update` only sees a release when that number changes; `version-packages`
 * runs `scripts/sync-plugin-version.mjs` to keep them in step), and the repo root
 * must not grow any other plugin component (`commands/`, `agents/`, `hooks/`,
 * `.mcp.json`, `.lsp.json`, `settings.json`), or every plugin install would silently
 * ship it. The skill's frontmatter `name` is pinned too: without it the installed
 * skill would be named after the cache directory, which is a version string.
 *
 * `claude plugin validate .claude-plugin/plugin.json` passes with one warning, that CLAUDE.md at
 * the plugin root is not loaded as plugin context. That is what a repo-root plugin looks like,
 * not a defect; `--strict` is therefore not the right mode for this repo.
 *
 * Pure filesystem reads against the real tree. Port: N/A.
