* Enforces config env var checks and improves startup handling
Ensures critical environment variables are validated during config resolution,
raising clear errors if missing. Improves server startup reliability by
verifying that backend services are listening and by terminating on
misconfiguration at launch. Adds more robust feedback to developers when
API startup fails, reducing silent misconfigurations and speeding up
troubleshooting.
* Initial plan
* Implement suggestions from PR #892: fix env var checks and improve error logging

- Add memory API endpoints for retrieving memory data:
- GET /api/memory - get current memory data
- POST /api/memory/reload - reload from file
- GET /api/memory/config - get memory configuration
- GET /api/memory/status - get config and data together
- Optimize MemoryMiddleware to only use user inputs and final
assistant responses, filtering out intermediate tool calls
- Add memory configuration example to config.example.yaml

- Use ExtensionsConfig.from_file() instead of cached config to always
read latest configuration from disk in LangGraph Server
- Add mtime-based cache invalidation for MCP tools to detect config
file changes made through Gateway API
- Call reload_extensions_config() in Gateway API after updates to
refresh the global cache
- Remove unnecessary MCP initialization from Gateway startup since
MCP tools are only used by LangGraph Server

The proxy was creating a temporary httpx.AsyncClient within an async context manager.
When returning StreamingResponse for SSE endpoints, the client was being closed before
the streaming generator could use it, causing "client has been closed" errors.
This change introduces a shared httpx.AsyncClient that persists for the application
lifecycle, properly cleaned up during shutdown. This also improves performance by
reusing TCP connections across requests.
