Function find_hidden_processes 

pub fn find_hidden_processes<P: PhysicalMemoryProvider>(
    reader: &ObjectReader<P>,
) -> Result<Vec<HiddenProcessInfo>>

Scan for processes hidden by DKOM or PID namespace tricks.

Delegates to crate::psxview::walk_psxview for the cross-view enumeration, then returns only entries where is_dkom_hidden is true.
