This implements the Core-Adapter Architecture for v3, separating framework-agnostic validation logic from transport-specific adapters. Key Features: - Core struct with CheckToken method for pure validation logic - Options pattern with error-returning option functions - Type-safe context helpers using generics (GetClaims[T]) - Unexported contextKey int to prevent collisions (Go best practice) - Structured error types with error codes - Logger interface for observability - 100% test coverage Changes: - Add core/core.go: Framework-agnostic validation engine - Add core/option.go: Options pattern with validation - Add core/errors.go: Structured errors and error codes - Add core/context.go: Type-safe context helpers - Add core/core_test.go: Comprehensive tests This enables future support for multiple frameworks (HTTP, gRPC, Gin, Echo, etc.) by wrapping the Core with transport-specific adapters. Part of PR 1.2 in v3 Phase 1 implementation.
