ConvertTo-LongPath short-circuits for ordinary long paths (no ~\d alias),
so $script:LastResolver is only assigned when a short path actually needs
expansion. The ResolvedPathReport block read it unconditionally, which is
fatal under Set-StrictMode before any install stage runs (#93017: fresh
installs died at line 367 through three different invocation styles).
Initialize it to 'none' — the resolver's own value for "nothing ran" — at
script scope before Set-LongProfileEnvVars can invoke a resolver.
