msgpackr-extract fails on Windows ARM64 / no win32-arm64 prebuild

[rLamonAC]

msgpackr depends on msgpackr-extract for native MessagePack acceleration.
msgpackr-extract ships prebuilt binaries for several platforms (win32-x64, darwin-arm64, linux-x64, linux-arm64, …) but not for win32-arm64.

On a native Windows ARM64 Node install, msgpackr-extract therefore tries to fall back to compiling from source. That fails for two independent reasons:

1. The node-gyp-build-optional-packages fork it uses passes process.execPath unquoted when shelling out to node-gyp rebuild, so a Node path like C:\Program Files\nodejs\node.exe is split at the space. This is the same root cause as upstream prebuild/node-gyp-build#71, which was fixed in prebuild/node-gyp-build#72, but that fix has not reached the node-gyp-build-optional-packages fork used here.
2. Even after working around the quoting issue (e.g. by moving Node to C:\nodejs), the build can still fail because the required MSVC toolset is unavailable (e.g. only v143 is installed while the build wants v145).

This was already reported in kriszyp/msgpackr-extract#14, but that repository appears much less active.

Could msgpackr either:

• publish an official win32-arm64 prebuild for msgpackr-extract, or
• make msgpackr-extract a truly optional dependency so install failures are ignored and msgpackr falls back to its pure-JS implementation?

Environment

• Node: 26.5.1
• OS: Windows 11 ARM64
• process.platform: win32
• process.arch: arm64
• msgpackr-extract: 3.0.4
