Refactor context handling in HandleCount and HandleReq functions

- Updated context creation in HandleCount and HandleReq to use context.Background() instead of the connection context, isolating timeouts to prevent affecting long-lived websocket connections.
- Improved comments for clarity on the purpose of the context changes.
- bump version to v0.17.17
