♻️ refactor: organize BDD steps by domain with JWT implementation

- Split steps into domain-specific files: - greet_steps.go: Greet API steps - health_steps.go: Health check steps - auth_steps.go: Authentication steps with full JWT implementation - common_steps.go: Shared validation steps - Add comprehensive README.md for steps organization - Implement all TODO items in auth_steps: - JWT claims verification for admin - JWT token validation and parsing - User ID extraction from tokens - Token comparison for consecutive authentications - Update main steps.go to register all domain steps Generated by Mistral Vibe.

+# BDD Steps Organization
+
+This folder contains the step definitions for the BDD tests, organized by domain for better maintainability and scalability.
+
+## Structure
+
+```
+pkg/bdd/steps/
+├── greet_steps.go        # Greet-related steps (v1 and v2 API)
+├── health_steps.go       # Health check and server status steps
+├── auth_steps.go         # Authentication and user management steps
+├── common_steps.go       # Shared steps used across multiple domains
+├── steps.go             # Main registration file that ties everything together
+└── README.md            # This file
+```
+
+## Design Principles
+
+1. **Domain Separation**: Steps are grouped by functional domain
+2. **Single Responsibility**: Each file focuses on a specific area of functionality
+3. **Reusability**: Common steps are shared via `common_steps.go`
+4. **Scalability**: Easy to add new domains as the application grows
+
+## Adding New Steps
+
+1. **For new domains**: Create a new `*_steps.go` file following the existing pattern
+2. **For existing domains**: Add to the appropriate domain file
+3. **For shared functionality**: Add to `common_steps.go`
+4. **Register all steps**: Update `steps.go` to include the new steps
+
+## Step Naming Convention
+
+- Use descriptive, action-oriented names
+- Follow the pattern: `i[Action][Object]` or `the[Object][State]`
+- Example: `iRequestAGreetingFor`, `theAuthenticationShouldBeSuccessful`
+
+## Testing the Steps
+
+Run BDD tests with:
+```bash
+go test ./features/... -v
+```
+
+## Future Domains
+
+As the application grows, consider adding:
+- `payment_steps.go` - Payment processing steps
+- `notification_steps.go` - Notification and email steps
+- `admin_steps.go` - Admin-specific functionality steps
+- `api_steps.go` - General API interaction patterns
