  "message": "Windows support 1/x: centipede:command.\n\n`Command` previously relied on `posix_spawn` with `/bin/sh`, the POSIX `env` utility for environment variable modifications, and shell `\u003c` redirection syntax in arguments. These mechanisms are not portable to Windows.\n\nRefactor `Command` to support native Windows process management alongside POSIX:\n\n- Introduce `Command::PlatformContext` to encapsulate platform-specific process handles (`HANDLE` on Windows vs. `pid_t` and `ForkServerProps` on POSIX).\n\n- Implement Windows process creation, environment block construction (`Options::env_diff`), and standard stream redirection in `Command::ExecuteAsync()` using `CreateProcessA`.\n\n- Add `Options::stdin_file_path` to handle input redirection directly rather than appending `\"\u003c\"` to command arguments, and update `SymbolTable` to use it.\n\n- Escape command-line arguments, environment variables, and file paths in `Command::ToString()` on both POSIX (`ShellEscape`) and Windows.\n\n- Update `command_test_helper` and `command_test` to verify arguments, environment variables, standard input, and signals portably without relying on `bash`, and enable `centipede:command_test` on Windows CI.\n\n- Update `GetDataDependencyFilepath` to return executable path suffixed with `.exe` under Windows.\n\nPiperOrigin-RevId: 959298250\n",
