[Bug] Manifest consistency not checked before/after autoupdate

[z-Fng]

Description

Manifest consistency check is not performed after a real force update (running checkver.ps1).

It only ensures that the update runs successfully, but does not guarantee that the manifest remains the same before and after execution.

This can lead to situations where incorrect manifests go unnoticed, potentially causing installation or autoupdate issues.

Steps to Reproduce

For instance, create a PR which incorrectly modify autoupdate.hash without running checkver:

• test consistency check z-Fng/Scoop-Extras#12
