fix: add null checks for runtime.context in middlewares and tools (#1269) 
Add defensive null checks before accessing runtime.context.get() to
prevent AttributeError when runtime.context is None. This affects:
- UploadsMiddleware
- MemoryMiddleware
- LoopDetectionMiddleware
- SandboxMiddleware
- sandbox tools
- setup_agent_tool
- present_file_tool
- task_tool

Also adds .env loading in serve.sh for environment variable support.
