Feature: Diff review should also read audit reports

[omarinuwa]

For the diff-review skill, if it is used for engagements where the original audit report is available and the changes were a direct consequence of the audit engagement, it may be useful for this skill to read the original audit report.

There is a slight difference between this type of differential review and one caused by feature additions and deletions.

There could be different "modes" the user can choose from, depending on the context of the differential review.

e.g "If post-audit review fix review, read audit report for context

if just checking against regular code changes and checking if it doesn't break anything, the normal mode can be used
