Get a single property value. psetName / propName accept Bonsai-style
/regex/ patterns (e.g. /Pset_.*Common/), so one call can read across
several matching property sets; a plain name is an exact match. Returns the
first match in set/property order.
Get a single quantity value. Supports 2-arg (ref, quantityName) or 3-arg
(ref, qsetName, quantityName). Qset / quantity names accept Bonsai-style
/regex/ patterns (e.g. /Qto_.*BaseQuantities/), so one call can read a
quantity across several matching sets; a plain name is an exact match.
Returns the first match in set/quantity order.
