Implement Robust Typed Middleware Chain with Dynamic Error Handling

middleware generics type-safety error-handling
Prompt
Design a generic middleware pipeline system for TypeScript that supports type-safe middleware chaining, with automatic error propagation and contextual type inference. Create an implementation that allows middleware to modify request/response types dynamically, supports async operations, and provides compile-time type safety. Include methods for middleware registration, execution order control, and comprehensive error management across different middleware stages.
