[Epic] Govern and optimize Azure estates

## Problem statement

After deployment, teams need coordinated cost, quota, reliability, compliance, access, policy, and infrastructure guidance. Treating these as unrelated checks hides tradeoffs and remediation priorities.

## Outcome

Teams can assess, govern, and optimize their Azure estates using evidence-based recommendations and safe remediation paths.

## Goals

- Combine cost, quota, reliability, compliance, RBAC, policy, and architecture signals
- Prioritize recommendations by impact and risk
- Provide safe, reviewable remediation guidance
- Verify material changes after execution

## Non-goals

- Applying consequential changes without confirmation
- Replacing Azure governance and management products

## Success criteria

- [ ] Assessments use current estate evidence
- [ ] Recommendations explain impact, risk, and dependencies
- [ ] Remediation workflows preserve least privilege and verify results

## Dependencies

Azure Advisor, Cost Management, Policy, RBAC, compliance, reliability, and resource inventory tools.

Start with the issue's goals, non-goals, and success criteria; no implementation files, tests, or entry points are identified. Review how Azure Advisor, Cost Management, Policy, RBAC, compliance, reliability, and resource inventory tools relate to the proposed assessment. Done means defining an evidence-based, prioritized governance workflow with safe remediation guidance and verification.
