The previous suite pulled ConvertTo-LongPath out of install.ps1 via the AST
and dot-sourced the extracted text. AGENTS.md bans source-reading tests, and
this one showed why: it never executed the script-level Add-Type the kernel32
resolver depends on, so the resolver that does the actual work was untestable
by construction.
Each case now spawns install.ps1 as a real subprocess with a crafted
environment. -ProtocolVersion is a side-effect-free early exit below the
normalization block, so the whole block runs exactly as it does mid-install
and the assertions read what it reports back.
Verified RED against the pre-fix install.ps1 (10 of 24 assertions fail) and
GREEN after. The profile-root substitution is pure path arithmetic, so those
cases run on any host including non-Windows CI.

Adds a ConvertTo-LongPath helper to install.ps1 that expands a Windows 8.3
short path (e.g. C:\Users\FIRST~1.LAS) back to its long form via
Scripting.FileSystemObject. Paths without a "~<digit>" component are returned
unchanged (no COM round-trip), and any COM failure falls back to the input.
Adds an AST-loaded unit test that exercises the helper without executing the
installer body (pass-through, null/empty, and graceful fallback).
