repo_get_pull_request_changes does not get the list of changes even when includeLineContent and includeDiffs are true

[krid-583]

SUMMARY :
repo_get_pull_request_changes does not consistently return the actual line content or diff payload even when includeDiffs=true and includeLineContent=true are requested. In the observed case, the response only included change metadata such as the file path and change type, which is a bug.

TOOL NAME:
repo_get_pull_request_changes

RULES:

• If the pull request contains changes where only new files are added, the tool should return the full file content and corresponding diff context, which doesn't happen.
• If the pull request contains changes where files are removed completely, the tool should return the removed content and corresponding diff context. This is another erroneous case.
