/// mise relays a task's output itself unless the task is `raw`, and appends an
/// SGR reset to every relayed line whenever its own colour is on.
/// `CLICOLOR_FORCE=1` turns that on into a pipe. The task runs in a scrubbed
/// environment, so neither the caller's mise configuration nor its colour
/// settings reach it.
