* enhance: Add safety features to HTTP validation tools response
- Add TypeScript interface (MCPToolResponse) for type safety
- Implement 1MB response size validation and truncation
- Add warning logs for large validation responses
- Prevent memory issues with size limits (matches STDIO behavior)
This enhances PR #343's fix with defensive measures:
- Size validation prevents DoS/memory exhaustion
- Truncation ensures HTTP transport stability
- Type safety improves code maintainability
All changes are backward compatible and non-breaking.
