feat: add comprehensive free tier integrations

Browse source 
AI Services (contributor's fork pays):
- Groq: 14,400 req/day (Llama 3.3 70B)
- Mistral: 1M tokens/month
- Cohere: 1000 req/month (classification)
- Cloudflare AI: 10K neurons/day
- Gemini: 1500 req/day (existing)

Security Scanners (100% free, no keys):
- Semgrep: SAST
- Trivy: Container/IaC vulns
- Gitleaks: Secret detection
- OSV-Scanner: Google vuln DB
- Checkov: IaC security

All results:
- Upload to GitHub Security tab (SARIF)
- Create artifacts for core CLI to consume
- Feed into Agentic task queue

Doc: free-tier-services.md lists 50+ free services
