Resolve import cycles and migrate to chorus.services module path

This comprehensive refactoring addresses critical architectural issues:

IMPORT CYCLE RESOLUTION:
• pkg/crypto ↔ pkg/slurp/roles: Created pkg/security/access_levels.go
• pkg/ucxl → pkg/dht: Created pkg/storage/interfaces.go
• pkg/slurp/leader → pkg/election → pkg/slurp/storage: Moved types to pkg/election/interfaces.go

MODULE PATH MIGRATION:
• Changed from github.com/anthonyrawlins/bzzz to chorus.services/bzzz
• Updated all import statements across 115+ files
• Maintains compatibility while removing personal GitHub account dependency

TYPE SYSTEM IMPROVEMENTS:
• Resolved duplicate type declarations in crypto package
• Added missing type definitions (RoleStatus, TimeRestrictions, KeyStatus, KeyRotationResult)
• Proper interface segregation to prevent future cycles

ARCHITECTURAL BENEFITS:
• Build now progresses past structural issues to normal dependency resolution
• Cleaner separation of concerns between packages
• Eliminates circular dependencies that prevented compilation
• Establishes foundation for scalable codebase growth
