[core] feat: integrate social intelligence orchestration

[mdabir1203]

Summary

• add the Codex social-intelligence configuration and engine so social signals, correlations, remediation guidance, and metrics are synthesized during scans
• wire social intelligence into the autonomous recon agent, report writers, CLI logging, and dashboard visuals, producing a social_intelligence.json artifact
• document the baked-in workflow, expose an override environment variable, and refresh dependencies to support YAML parsing

Testing

• cargo clippy --workspace --all-targets -- -D warnings
• cargo test --workspace --locked
