Pull Request Overview
This pull request implements new CodeQL queries to enforce MISRA-C++23 preprocessor rules (RULE-19-0-4, RULE-19-1-1, and RULE-19-2-1), and it adds test cases to verify improper include guards and misuse of the preprocessor.
- Added test files with intentionally malformed include guards and misuse of the "defined" operator.
- Created new QL query files to detect violations of MISRA preprocessor rules.
- Updated common utilities and exclusion lists to support preprocessor-related queries.

Release change checklist
A change note (development_handbook.md#change-notes) is required for any pull request which modifies:
If you are only adding new rule queries, a change note is not required.
Author: Is a change note required?
🚨🚨🚨
Reviewer: Confirm that format ofshared queries (not the .qll file, the
.ql file that imports it) is valid by running them within VS Code.
Reviewer: Confirm that either a change note is not required or the change note is required and has been added.
Query development review checklist
For PRs that add new queries or modify existing queries, the following checklist should be completed by both the author and reviewer:
Author
As a rule of thumb, predicates specific to the query should take no more than 1 minute, and for simple queries be under 10 seconds. If this is not the case, this should be highlighted and agreed in the code review process.
