🎉 Full Go Generics Support

This release adds complete support for Go generics (type parameters), enabling gotests to generate tests for generic functions and methods on generic types.

✨ Key Features

• 🔧 Generic Functions: Generate tests for functions with type parameters go func FindFirst[T comparable](slice []T, target T) (int, error)

• 🏗️ Generic Types: Support for methods on generic types go type Set[T comparable] struct { ... } func (s *Set[T]) Add(v T)

• 🎯 All Constraint Types: any, comparable, union types (int64 | float64), approximation (~int)

• 🧠 Smart Type Mapping: Intelligent defaults for type instantiation

• any → int
• comparable → string
• Union types → first option

• Approximation → underlying type

• 🔄 Multiple Type Parameters: Handles functions like Pair[T, U any]

📊 Test Coverage

• ✅ 97.5% main package coverage
• ✅ 83.5% overall project coverage
• ✅ 100% coverage on all new parser functions
• ✅ 8 comprehensive generic test patterns

🔧 Technical Improvements

Parser Enhancements: - New parseTypeDecls() extracts type parameters from type declarations - New parseTypeParams() parses AST field lists - New extractBaseTypeName() handles receiver types

Template Functions: - TypeArgs - generates concrete type arguments for calls - FieldType - substitutes type parameters in field declarations - ReceiverType - substitutes type parameters in receiver instantiations

Model Updates: - New TypeParam struct - Added TypeParams field to Function - Helper methods: IsGeneric(), HasGenericReceiver()

📚 Documentation

Added comprehensive "Go Generics Support" section to README with: - Example: Generic function test generation - Example: Methods on generic types - Type constraint mapping reference
