feat(api): Add Policy Registry API specification

- Introduced OpenAPI specification for the StellaOps Policy Registry API, covering endpoints for verification policies, policy packs, snapshots, violations, overrides, sealed mode operations, and advisory staleness tracking.
- Defined schemas, parameters, and responses for comprehensive API documentation.

chore(scanner): Add global usings for scanner analyzers

- Created GlobalUsings.cs to simplify namespace usage across analyzer libraries.

feat(scanner): Implement Surface Service Collection Extensions

- Added SurfaceServiceCollectionExtensions for dependency injection registration of surface analysis services.
- Included methods for adding surface analysis, surface collectors, and entry point collectors to the service collection.
