When a command is run, Peace stores information about that execution.

It stores this in a .peace directory within a workspace directory. The automation tool developer needs to tell Peace how to determine the workspace directory.

let cmd_ctx = CmdCtx::builder_single_profile_single_flow
    ::<EnvManError, _>(output, workspace)
    // ..
pub enum WorkspaceSpec {
    /// Use the exe working directory as the workspace directory.
    /// The working directory is the directory that the user ran the program in.
    /// Use a specified path.
    /// Traverse up from the working directory until the given file is found.
    /// The workspace directory is the parent directory that contains a file or
    /// directory with the provided name.
