Pull request overview

This PR introduces a new daytona sandbox variant (DaytonaSandbox) that runs code inside Daytona cloud sandboxes via a stateful interpreter (preserving Python state across calls), and wires it through the library’s provider/manager/CLI layers with corresponding docs and examples.

Changes:

• Add DaytonaSandbox implementation (stateful interpreter execution, contexts, network/resources mapping, filesystem integration).
• Add Daytona management support (get_manager("daytona") CRUD) and provider registration, plus CLI support.
• Add extensive unit tests and update docs/examples/README/changelog to document and demonstrate the new variant.
