 * The shell OpenCode's bash tool will actually run, mirrored from OpenCode's
 * `Shell.acceptable(cfg.shell)` (packages/core/src/shell.ts, stable since 1.4.0;
 * `cfg.shell` is honored from 1.14.27). Command prefixes must use this shell's
 * syntax: inferring it from ComSpec picks cmd on machines where OpenCode runs
 * PowerShell (#9733).
 *
 * Order: the configured `shell`, else `$SHELL`, when it is not fish/nu and
 * resolves to a file; otherwise on Windows the first of pwsh, powershell,
 * Git Bash, then COMSPEC (or cmd.exe); elsewhere /bin/zsh on macOS, then bash,
 * then /bin/sh.
