Mine the phase* port batteries into the spec layer and delete them (their
behavior is now covered by spec): phase5 (hierarchies), phase6 (tagged
literals/reader-conditionals), phase7 (lazy/sets), phase8+phase12 (protocols;
phase12 was a duplicate of phase8), phase10 (strings/set), phase13
(reify/walk). Unique cases mined into spec: reader #inst/#uuid/#?@ splice,
(Type. args) dot constructor, lazy-seq body-runs-once, keywordize-keys/
stringify-keys, custom :default key and explicit :hierarchy dispatch.
phase6-final tested the COMPILE-MODE path ({:compile? true}), distinct from the
interpreter-based spec — kept and renamed integration/compile-mode-test.

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.
