Subject: [PATCH] Implement Phase 4: Advanced dependency resolution features

- Add dependency_resolver module with advanced conflict detection
- Implement DependencyResolver with circular dependency detection
- Add package metadata structures (DebPackageMetadata, DependencyConstraint)
- Integrate dependency resolution into lib.rs exports
- Support for dependency tree resolution and validation
- Conflict detection with severity levels (Critical, Warning, Info)
- Known system conflict detection (mail servers, display managers, init systems)
- Generate comprehensive dependency resolution reports
