Struct CommandContext 

pub struct CommandContext<'a> {
    pub fs: &'a dyn VirtualFs,
    pub cwd: &'a str,
    pub env: &'a HashMap<String, String>,
    pub stdin: &'a str,
    pub stdout: &'a mut String,
    pub stderr: &'a mut String,
    pub exec_fn: Option<&'a dyn Fn(&str) -> Result<ExecResult, Error>>,
    pub limits: &'a ExecutionLimits,
}

Provides filesystem, environment, and I/O access to commands.

Commands receive this as &mut so they can write to stdout/stderr. The filesystem and environment are borrowed from the interpreter.
