Claude Code 2.1.131: Windows Extension & Auth Fixes

TL;DR

  • Fixed VS Code extension activation failure on Windows
  • Fixed Mantle endpoint authentication with missing API key header

Fixed

  • VS Code extension Windows activation — Extension was failing to activate on Windows due to a hardcoded build path in the bundled SDK's createRequire polyfill. Now works correctly across platforms.
  • Mantle endpoint authentication — Fixed missing x-api-key header causing authentication failures when connecting to Mantle endpoints.
