Sigil 0.2.8.10

Fixed

• Race condition in hydration guards: Fixed race condition where concurrent hydrateFromDOM() calls could both pass guards and create two GPUDevice instances
  • Moved all guard checks to run synchronously before scope.launch
  • Added hydrationInProgress set to block concurrent hydrations immediately
  • The hydratedCanvases set now tracks completed hydrations; hydrationInProgress tracks in-flight ones

Added

• Hydration guard unit tests: New HydrationGuardLogicTest with 9 tests verifying:
  • Single and double hydration blocking
  • Race condition prevention (concurrent calls blocked by in-progress check)
  • Force reinitialization bypass
  • Failed hydration cleanup and retry
  • Multiple canvas independence
