[Bug] regorus_ffi.dylib missing from osx-arm64 package in 0.5.0-preview1 — crashes on macOS Apple Silicon

Description

@microsoft/workiq@0.5.0-preview1 crashes immediately on macOS (Apple Silicon / osx-arm64) with an unhandled exception because regorus_ffi.dylib is not included in the npm package.

Error

Unhandled exception: System.DllNotFoundException: Unable to load shared library 'regorus_ffi'

dlopen(.../node_modules/@microsoft/workiq/bin/osx-arm64/regorus_ffi.dylib, 0x0001):
tried: '...' (no such file)

Root cause

The file bin/osx-arm64/regorus_ffi.dylib (and likely bin/osx-x64/) is absent from the published npm package. The Windows equivalents (regorus_ffi.dll) are present in bin/win-x64/ and bin/win-arm64/, so this appears to be a packaging oversight.

Steps to reproduce

npx -y @microsoft/workiq@0.5.0-preview1 mcp

Environment

• Platform: macOS Apple Silicon (arm64)
• Node: via npx
• Package version: @microsoft/workiq@0.5.0-preview1

Workaround

Pin to the previous stable version, which does not have this dependency:

npx -y @microsoft/workiq@0.4.1 mcp

Additional notes

Also related: issue #124 notes that 0.5.0-preview1 is not tagged as preview on npmjs.org, so users installing @latest silently get this broken version on macOS with no clear error message pointing to the cause.

Reproduce the failure with npx @microsoft/workiq@0.5.0-preview1 mcp and inspect the published package's bin/osx-arm64 and bin/osx-x64 directories. Compare them with bin/win-x64 and bin/win-arm64 and trace the npm packaging configuration. Done means the required macOS dylibs are included in the published package and the command starts on Apple Silicon.
