Add agentic AI GRC automation solution blueprint

[Rahulthespy]

Motivation

• Provide a complete design blueprint for an agentic AI platform to automate Governance, Risk, and Compliance (GRC) aligned to ISO 27001, ISR, GDPR, PCI DSS, and Business Continuity requirements.
• Capture architecture, data model, multi-agent orchestration, scanning/mapping, audit workflows, dashboards, predictive recommendations, and security/trust controls to guide implementation.
• Offer an actionable execution plan and examples to accelerate building a CISO Assistant-style system that integrates with existing enterprise tooling.

Description

• Added docs/grc-agentic-solution.md containing the product vision, target architecture, data model, multi-agent design, control registry/versioning, mapping to NIST/ICS, API examples, and KPI targets.
• Added docs/solution-quickstart.md with a phased quickstart implementation plan covering foundation, operations, intelligence, and enterprise hardening steps.
• Replaced the repository README.md with a focused project overview that links to the new design documents and summarizes the platform scope and capabilities.
• Documented example API endpoints, integrations, and an implementation roadmap to mirror the structure and intent of a CISO Assistant-style solution.

Testing

• Verified file contents by printing and paginating the new files with cat README.md and nl -ba docs/grc-agentic-solution.md | sed -n '1,260p' and nl -ba docs/solution-quickstart.md | sed -n '1,200p', all of which returned the expected documentation sections.
• Confirmed the new files exist in the repository tree and are readable via local file listing commands, which succeeded.
• Created a PR record for these changes using the repository make_pr tool, and the PR payload was generated successfully.
