feat: implement remote execution environment backends (SSH, Modal, Daytona) (fixes #1395)
- Added SSHSandbox for remote server execution via SSH with asyncssh - Added ModalSandbox for serverless GPU execution on Modal platform - Added DaytonaSandbox for cloud development environment execution - Updated sandbox __init__.py with lazy loading for new backends - Added optional dependencies: [ssh], [modal], [daytona] in pyproject.toml - Created comprehensive unit tests for all new sandbox backends - Added examples/python/sandbox_remote.py with usage demonstrations - All backends implement complete SandboxProtocol interface - Follows protocol-driven architecture with implementations in wrapper package 🤖 Generated with [Claude Code](https://claude.ai/code) Co-authored-by: MervinPraison <[email protected]>
