Add spec suites for stateful refs (atoms/volatiles/delays/promises), multimethods (dispatch + hierarchies), and protocols/types/records. Bugs caught and fixed: - reify with multiple methods registered only the first (stepped i by 2 over one-element specs); now collects every method spec - get-method/methods/remove-method evaluated their arg to the dispatch fn, but a multimethod's methods live on its var — now resolve the var (get-method and methods are special forms; remove-method fixed). get-method/methods added. - no global hierarchy: 2-arg derive modified a throwaway, isa? was hardcoded false, parents missing, ancestors/descendants returned arrays (so contains? failed), and dispatch ignored derive. Now a global hierarchy backs the 1/2-arg derive/isa?/parents/ancestors/descendants (returning sets) and multimethod dispatch falls back to it. Corrected a phase5 port assertion that encoded the old isa? bug. conformance 218/218, jpm test green.
