v0.2.0

Added

• Three new checks, enabled by default:
  • hardport — hardcoded TCP/UDP ports in test listeners.
  • maporder — assertions that depend on map-iteration order.
  • eventuallyeffect — count-dependent side effects inside polling callbacks.
• version command: flakylint version (also --version / -version) prints
  the build version, commit, and date, falling back to
  runtime/debug.ReadBuildInfo when built without release ldflags.

Changed

• Autofix safety: suggested fixes are no longer offered when they would corrupt
  the source. httptestclose keeps the diagnostic but drops the fix inside
  if/for/switch statement initializers; exitfatal suppresses its fix when
  the testing receiver name is shadowed at the call site.
• Precision narrowing from corpus evaluation and an external audit:
  hardport validates the network argument and port range and no longer flags
  http.Server{Addr:} literals; eventuallyeffect ignores channels declared
  inside the callback; maporder is now source-order aware and ignores
  per-iteration accumulators used only as testify message arguments.

Upgrade notes

• The new default-enabled checks may surface findings in downstream CI that
  previous versions did not report. Pin @v0.2.0 in CI installs (rather than
  @latest) so a future release does not change results unexpectedly.
