Production-grade resilience patterns for ZeroThrow

# Changelog

## 0.2.1 - 2025-07-07

### Patch Changes

- Fixed workspace protocol dependencies for npm compatibility
  - Replaced `workspace:*` with actual version numbers in devDependencies
  - This resolves npm installation issues when packages are published

## 0.2.0 - 2025-07-07

### Breaking Changes

- **Policy hierarchy refactored**: `Policy` is now the base type with specific subtypes:
  - `RetryPolicy`
  - `CircuitBreakerPolicy`
  - `TimeoutPolicy`
- **Policy renamed to PolicyFactory**: The main factory class is now `PolicyFactory`
- **New callback methods added**:
  - `onRetry`: Callback for retry events
  - `onCircuitStateChange`: Callback for circuit breaker state transitions

### Migration Guide
- Replace `Policy.retry()` with `PolicyFactory.retry()`
- Replace `Policy.circuitBreaker()` with `PolicyFactory.circuitBreaker()`
- Replace `Policy.timeout()` with `PolicyFactory.timeout()`
- Update type imports if using specific policy types

## 0.1.1

### Patch Changes

- Updated peer dependency for @zerothrow/core to support v0.2.0
  - Changed from `^0.1.0` to `>=0.1.0` (peer deps) or `^0.2.0` (regular deps)
  - This allows the package to work with core v0.2.0 without warnings
