…sions

init.ps1 now resolves the exact installed version satisfying the Version input, removes any already-loaded GitHub module versions from the session, and imports the resolved version with -RequiredVersion -Global — so the user script uses the selected version instead of whatever PowerShell would auto-load from PSModulePath.

…loaded instances

Per PR review: resolution now excludes prerelease versions when Prerelease is false and adds a stable-wins tie-breaker (so a Prerelease:false run never imports an installed prerelease, and stable wins at equal base version); and 'Get-Module -Name \ -All | Remove-Module' removes every loaded instance before import.

…r error

Filter/sort on the 'Prerelease' string instead of IsPrerelease; add -ErrorAction Stop to the final Import-Module so a failed load stops the run; and render 'latest' in the throw message when no Version was requested (matching the moduleStatus display).

…stable request

When Prerelease is false, exclude prereleases from the already-installed check so a machine with only prerelease builds installed still installs a stable version instead of failing resolution.

…matches

Normalize the already-installed set to \ when the (prerelease-filtered) query returns nothing, so the '-not' install guard and the '\ -ne' moduleStatus check both retain their original meaning instead of an empty array reading as 'installed'.
