v0.1.5

v0.1.5 — output quality: real local names + compilability fixes

• Real local-variable names from debug_info (type-gated, cross-block
  unified): s() now reads String s(byte[] enc, int k) with out/i.
• Lab-package feedback fully root-caused: 0 javac errors (0.1.4: 39).
• javac full-compile gate fixes: nested-class name-chain renames
  (lark already-defined 22316 -> 93), nested reference prefixes,
  catch-parameter double declaration, super() ordering, duplicate
  covariant methods (weibo 14871 -> 971).
• Perf round: weixin 18.2 -> 10.6s, qq -25%, WhatsApp -38%;
  deterministic output run-to-run.
• jdc-core 0.2.0, ddc-dex 0.2.1.
