Promotes the new HTTP Archive agent plugin for Claude Code and Codex: BigQuery skills plus the Tech Report MCP server at https://cdn.httparchive.org/mcp.

Changes:

• New guide docs/guides/ai-agents: install for Claude Code, Codex and other agents; adding only the MCP server; tables of MCP tools and skills; requirements, including a cost caution suggesting a BigQuery custom quota; example prompts. Added to the Guides sidebar.
• Docs home: "Use with AI Agents" card under Guides & Tutorials.
• Home page: new "AI Agents · Agents Plugin" section after the BigQuery section, with a terminal-style panel of install commands in place of an illustration (hidden on phones, like the other illustrations), plus buttons to the guide and the GitHub repo.
• CSS: reusable .terminal, .terminal-comment and .terminal-prompt styles in styles.css.
• Per-page Markdown: adds starlight-md-txt 0.2.0, so every docs page is also served as Markdown at its URL plus .md (for example /docs/guides/minimizing-costs.md), following the llms.txt convention. absoluteLinks: true makes those files work outside the site: links to other docs pages point to their .md files, other links and images (/_astro/…) are absolute https://httparchive.org URLs. No 404.md is generated, and no <link rel="alternate"> tags are added. Firebase already serves .md as text/markdown, so firebase.json is unchanged.
• Guide requirements: the BigQuery skills now need only bq; docs are read with the agent's built-in web fetch instead of gh and curl.

Generated files (config/last_updated.json, public/sitemap.xml) are left to the usual generation PRs.

Checked locally: npm run build passes, all internal links are valid, and htmlhint reports no errors on the changed pages.

• Plugin repo: HTTPArchive/httparchive-plugin. It holds the skills, the marketplace files for Claude Code and Codex, and the MCP config, and its CI installs the plugin into both harnesses. The install commands in this PR come from its README.
• Update minimizing-costs guide: rank estimates are now accurate #1379 updates the minimizing-costs guide, which the plugin's query-optimizer skill follows.

LGTM with two suggestions to consider. Think we should definitely do the “consider” -> “strongly recommend” suggestion but more open to the the “caution” -> “danger” one.

Not seeing the parent GCP project for queries still gives me a cold sweat, so I'd say 'danger' for sure.
