- Fix missing SystemPrompt field in sandbox executor options conversion
(was causing Claude CLI to be skipped even when prompts were configured)
- Rewrite parseStream to handle Claude CLI stream-json output format:
- system: initialization message
- assistant: message with content array (text, tool_use)
- result: final result with verification string
- Add comprehensive E2E tests via caller for sandbox integration:
- TestSandboxE2E_ClaudeCLIExecution: verify command execution
- TestSandboxE2E_FileCreation: verify file operations
- TestSandboxE2E_HookOnlyMode: verify Claude CLI skip logic
- TestSandboxE2E_StreamingResponse: verify streaming works
- Add real_e2e_test.go for direct Claude CLI execution testing
