Personal AI Router 0.1.1

Fixed

• Building from source for an Intel/AMD (x64) target failed while compiling the
  bundled log sanitizer. The packaging script passed Electron's x64
  architecture name straight to the Go toolchain, which expects amd64. Arm64
  targets were unaffected.

Notes

This release contains no application changes. The fix is to the build tooling
only, and the published 0.1.0 installers were not affected by it, so 0.1.1 is
functionally identical to 0.1.0 for anyone installing it.
