refactor: remove SSE transport support from code and documentation (#97)

- Remove support and documentation for sse mode across all language README files
- Update CLI flags and help text to exclude references to sse mode
- Remove SSE server initialization in operation logic
- Adjust error messages to only mention stdio and http transport types
- Update logging setup to remove sse mode conditional logging

See the latest documentation: https://modelcontextprotocol.io/specification/2025-06-18/basic/transports
