Pull Request Overview

This pull request updates the .gitignore to exclude local Claude runtime artifacts and Codacy instruction files. While the implementation satisfies the acceptance criteria, there is a concern regarding the exclusion of files within the .github/ directory, as these are typically intended to be shared across the team. Codacy analysis indicates that the changes are up to standards with no new quality issues introduced.

Test suggestions

• Confirm that files inside the .claude/ directory (e.g., .claude/scheduled_tasks.lock) are ignored by git.\n- [ ] Confirm that the file .github/instructions/codacy.instructions.md is ignored by git.

Prompt proposal for missing tests

Consider implementing these tests if applicable:
1. Confirm that files inside the .claude/ directory (e.g., .claude/scheduled_tasks.lock) are ignored by git.\n- [ ] Confirm that the file .github/instructions/codacy.instructions.md is ignored by git.

_{🟡 MEDIUM RISK}

Files in the .github/ directory are typically meant to be shared with the team. If these instructions are intended to guide AI behavior for the project, they should likely be committed rather than ignored. If they are personal/local overrides, they should reside outside of the .github/ directory.
