Azure Deployment Preflight Validation

Validates Bicep deployments to Azure before execution, detecting syntax errors, permission issues, and previewing infrastructure changes.

- Supports both Azure CLI (az) and Azure Developer CLI (azd) workflows, auto-detecting project type via azure.yaml

- Runs Bicep syntax validation, what-if analysis across all deployment scopes (resource group, subscription, management group, tenant), and permission checks with fallback to reduced-permission validation

- Captures detailed what-if results categorizing resources as create, delete, modify, or unchanged, with specific property changes for modified resources

- Generates a structured Markdown report in the project root documenting all validation steps, issues, recommendations, and deployment preview
