Add 5 MCF Agentic agent skills

[Cameron48]

Summary

Adds 5 production-ready agent skills from MCF Agentic, designed for autonomous AI agents operating in sales, service, and marketing workflows:

• lead-gen-pipeline — 6-agent autonomous pipeline that researches industries, finds businesses, identifies pain points, and generates personalized outreach
• crm-engine — Full CRM with accounts, leads, deals, contacts, pipelines, and work orders
• email-engine — Transactional email, bulk campaigns, AI classification, auto-reply generation, and template management
• scheduling-engine — Appointment booking, staff management, availability windows, and conflict detection
• ads-optimizer — Campaign audits, optimization analysis, A/B testing, and anomaly detection

All skills use x402 micropayments (USDC on Base L2) for authentication — no API keys needed. Each skill follows the repository's SKILL.md format with YAML frontmatter, endpoint documentation, request/response examples, use cases, and pricing tables.

Why these skills matter

These are tools built for the agent-to-agent economy. Any AI agent can discover a business vertical, research prospects, generate outreach, book meetings, manage deals, run ad campaigns, and close — all autonomously, all via API.

Checklist

• Each skill is in its own skills/<name>/ directory
• Each contains a SKILL.md with proper frontmatter
• Names use kebab-case matching directory names
• Complete endpoint docs with request/response examples
• Use cases and pricing tables included
