Code Review

This pull request introduces a new _should_ignore helper function in version_scanner.py to handle wildcard and path-based ignore patterns during repository scanning, along with corresponding unit tests. The review feedback highlights critical correctness and performance issues in the implementation of _should_ignore. Specifically, it identifies a performance overhead from redundant string operations on every file, a trailing slash bug where directory-only patterns fail to match, and a leading slash anchoring bug that incorrectly matches subpaths. The reviewer provides actionable suggestions to resolve these issues by preprocessing and caching patterns using functools.lru_cache, introducing an is_dir parameter to distinguish files from directories, and adding robust test cases to verify these edge cases.
