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.
jpm test green, conformance 218/218.
