Pull request overview

Updates the PowerShell hugo alias wrapper to more closely match the behavior of the other shell aliases by resolving the correct Hugo executable path via hvm status, falling back to hvm use, and finally to a system-installed Hugo.

Changes:

• Refactors Hugo-Override to prefer hvm status --printExecPathCached, then --printExecPath + hvm use --useVersionInDotFile, then system hugo.
• Ensures the resolved Hugo binary is always invoked at the end with argument splatting.
• Forces the hugo alias mapping to Hugo-Override.
