v0.1.8

v0.1.8 — quality rounds 59-64 + determinism hardening

Code quality (gold standard: full javac + android.jar, 4 real-world APKs):

• LOCAL-OK-gated renames for field-obscured nested types (JLS 6.4.2
  shadow family, flutter g$i shape): a full-corpus dex reference scan
  (new refscan module) gates each rename to provably file-local blast
  radius, plus the shadow-package twin rule. Ungated global renaming
  was measured catastrophic on conflict-dense corpora (weibo +36916).
• Conditional-super restructuring, 5 mechanical shapes: if/else branch
  merge with per-arg ternaries, straight-line inline-hoist, duplicate
  delegation dedup (R8 path-duplicated Kotlin default-arg bridges),
  throw-guard branches, chained guards via recursive normalization.
  "super must be first statement" errors: 513 -> 142.
• Enum constant ctor args resolved through clinit reaching-definitions
  (R8 register reuse across constant constructions): no more
  DEBUG(var0) dummy-name garbage.
• Static-field owner on synthetic holders prints the concrete anonymous
  name (LongMath$1.$SwitchMap$..., was Object.$SwitchMap$...).

Determinism (byte-identical output across runs restored):

• Root cause: a process-wide shared fallback VarInfo cached whichever
  dangling var id hit it first (jdc-core) — now per-id.
• Accessor code snapshotted before image retirement (inline_accessors
  cross-image reads raced retirement).
• CodeItem::parse only reads the catch-handler list when tries exist
  (spec 8.3.1) — exact-sized snapshots used to fail parsing, silently
  disabling accessor inlining corpus-wide.
• jdc-core walk gains a deterministic work budget (Σ universe per
  visit) behind the wall-clock backstop.

Gold standard totals (vs v0.1.7): reqable 15987 -> 14658,
weibo 155335 -> 154560, lark 68842 -> 64222, weixin 298275 -> 297003
(net -7996). Decomp times unchanged (weibo ~6.5s, weixin ~12s).
67 tests green; zero compiler/clippy warnings in ddc + jdc-core 0.2.3
(its never_loop correctness lint fixed); jdc-core bumped to 0.2.3.
