Implement Comprehensive TypeScript Type Safety Architecture

Summary

This PR transforms the codebase from loose TypeScript to a comprehensive, strict type-safe architecture. The changes establish a robust foundation with systematic type safety, comprehensive interface definitions, and modern architectural patterns including event systems, CRUD utilities, and RPC interfaces.

Key Changes

• Enable strict TypeScript compilation with noImplicitAny, strictNullChecks, strictFunctionTypes, and noImplicitReturns
• Implement comprehensive type system with branded types, domain models, and API contracts
• Add type-safe event system with interfaces for entity events and middleware
• Create generic CRUD patterns with utility types and repository interfaces
• Establish component boundaries with strict typing and dependency injection
• Add runtime API validation with transformation middleware
• Configure TypeScript project references for better build organization

Impact

This architectural overhaul provides:

• Type Safety: Eliminates implicit any types and enforces strict null checks
• Better Developer Experience: Clear interfaces and compile-time error catching
• Maintainability: Systematic organization with project references and component boundaries
• Scalability: Generic patterns for CRUD operations and event handling
• Runtime Safety: API validation and transformation middleware
