Add adlicio

[daniel-ddtech]

What kind of change is this?

• New catalog entry
• Fix a broken/outdated entry
• Other (README, CONTRIBUTING, infra, etc.)

Checklist (for new entries)

• The linked repo resolves and is not empty/archived.
• It's genuinely about Grok Bot (xAI + Cursor's cloud-computer product), not Grok Build or an unrelated same-named bot.
• It's not already listed anywhere in this README.
• The entry follows the exact format.
• It's placed alphabetically within the correct category.

Anything else maintainers should know?

Adlicio is a customer-voice research product. The linked repo is the plugin bundle, not the product marketing site: it ships .grok-plugin/plugin.json and .cursor-plugin/plugin.json alongside .claude-plugin/, .codex-plugin/ and a root plugin.json on the open agent-plugins.org schema, so it loads through the Cursor plugin and MCP policy that Grok Bot inherits. Components are one hosted MCP server at https://mcp.tryadlicio.com/mcp and one SKILL.md. No hooks, no local process, no API key: auth is OAuth 2.1 with dynamic client registration.

A parallel entry is open at xai-org/plugin-marketplace#488. Tagged production because the MCP server is live and paid-for by real users, not a demo. Happy to switch it to beta if you would rather hold that tag until the marketplace PR lands.
