Function peel_simple_command_loose 

pub fn peel_simple_command_loose(cmd: &Command) -> Option<PeeledCommand>

Looser cousin of peel_simple_command that ignores per-command redirects, leading variable assignments, and embedded subshells. Used by crate’s downstream consumers (agent-tools::approval) when the containing rule has already opted into those shapes via flags like allow_redirects — at that layer we still want to extract the primary command name so each pipeline stage can be matched.
