Introduce ZapDiff

[AryaHassanli]

ZapDiff is a tool to compare two sets of generated ZAP XMLs and report mismatches. Ultimately, this tool will be used to prevent SDK PRs to be merged if there are any inconsistencies in ZAP XML files with respect to the latest alchemy-generated XMLs.

Summary of Changes

Hello @AryaHassanli, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces ZapDiff, a new command-line tool designed to ensure the integrity and consistency of ZAP XML files. By comparing two distinct sets of these XMLs, it pinpoints discrepancies in elements, attributes, and file presence, outputting a detailed report in CSV format. This functionality is a critical step towards automating checks that prevent the merging of SDK pull requests containing inconsistent ZAP XML data, thereby enhancing code quality and reliability.

Highlights

• New zap-diff Command: Introduces a new command-line utility zap-diff to compare two sets of ZAP XML files.
• Inconsistency Reporting: The tool identifies and reports mismatches between the XML files, categorizing them by type and severity.
• CSV Output: Mismatches are outputted to a mismatches.csv file, providing a structured report.
• Preventative Measure: Ultimately intended to prevent SDK PRs from being merged if ZAP XML files are inconsistent with alchemy-generated versions.

Code Review

This pull request introduces ZapDiff, a new tool for comparing ZAP XML files. The implementation adds a zap-diff command to the CLI and a zapdiff package containing the core logic. My review focuses on correctness, performance, and adherence to Go best practices. I've identified several issues, including error handling bugs that could swallow errors, a potential panic due to a missing nil check, and opportunities for performance improvements in file list processing. I've also included suggestions for more idiomatic logging and fixing some typos.

Code Review

This pull request introduces ZapDiff, a new tool for comparing ZAP XML files. The implementation is well-structured, with a new zap-diff command and a dedicated zapdiff package for the core logic. The code is generally clean and follows good practices.

I've found two related high-severity issues in the core diffing logic that would lead to incorrect results:

1. The text content of XML elements is not being compared.
2. The unique ID generation for some elements incorrectly includes the text content, which would report text changes as additions/deletions rather than modifications.

Fixing these will significantly improve the accuracy of the tool. Details and suggestions are in the specific comments.
