v1.4.0

v1.4.0 — Architecture Documentation & Enterprise Hardening

New Documentation

• Architecture Document (docs/ARCHITECTURE.md) — comprehensive technical
  description of the library internals: bytecode instrumentation pipeline,
  freeze/restore data flow, JDWP port discovery, thread safety model,
  serialization format, and error handling strategy

• Code Audit (docs/CODE_AUDIT.md) — 19 findings across 4 severity levels
  covering potential bugs, robustness improvements, simplification opportunities,
  and enterprise hardening items

Bug Fixes & Hardening

• GC protection retry loop — JdiLocalSetter.disableCollection() now retries
  up to 5 times when ObjectCollectedException is thrown during the narrow window
  between JDI resolve and object pinning. Previously, a single retry was attempted
  and if it also failed, the restore silently proceeded with an unpinned reference.
  Now throws a clear error after exhausting all attempts. This hardens restore
  against extreme GC pressure (e.g., ZGC with small regions under heavy allocation).

Tests

All 258 tests pass (215 unit + 43 E2E).
