Integrate the ported sandbox system with Agent V2 node:
- Add DIFY_SANDBOX_CONTEXT_KEY to app_invoke_entities for passing
sandbox through run_context without modifying graphon
- DifyNodeFactory._resolve_sandbox() extracts sandbox from run_context
and passes it to AgentV2Node constructor
- AgentV2Node accepts optional sandbox parameter
- AgentV2ToolManager supports dual execution paths:
- _invoke_tool_directly(): standard ToolEngine.generic_invoke (no sandbox)
- _invoke_tool_in_sandbox(): delegates to SandboxBashSession.run_tool()
which uses DifyCli to call back to Dify API from inside the sandbox
- Graceful fallback: if sandbox execution fails, logs warning and returns
error message (does not crash the agent loop)
To enable sandbox for an Agent workflow:
1. Create a Sandbox via SandboxBuilder
2. Add it to run_context under DIFY_SANDBOX_CONTEXT_KEY
3. Agent V2 nodes will automatically use sandbox for tool execution
46 existing tests still pass.
