Function reconcile_bool_pairs 

pub fn reconcile_bool_pairs(
    matches: &ArgMatches,
    bool_pairs: &[BoolFlagPair],
) -> HashMap<String, Value>

Reconcile –flag / –no-flag boolean pairs from ArgMatches into bool values.

For each BoolFlagPair:

• If –flag was set → prop_name = true
• If –no-flag set → prop_name = false
• If neither → prop_name = default_val
