core pin: 0.1.5 — 0.1.4 dropped live code

jdc-core 0.1.4's structure.rs walk rewrites delete statements (rt.jar
140/12,609 units, JDK 26 image 166/15,231; e.g. ReentrantMutex.attempt's
whole try/wait/catch body collapsed to one call, and
ConcurrentSkipListMap.equals lost two `return false;`). 0.1.5 reverts that
file to its 0.1.3 content and keeps 0.1.4's other optimizations — verified
byte-identical to 0.1.3 on both corpora (rt.jar 12,609/12,609, JDK 26 image
15,231/15,231).

Gates on this pin: features battery 59/59 walk + 59/59 SESE, workspace tests
green, offline corpus 1 syntax-bad (the unspellable-name baseline), rt.jar
output identical across two runs (determinism) and identical to the 0.1.3
baseline tree.
