Fixes #627

cache_invalidation_files patterns are matched with fnmatch, where **/ requires a literal slash. A pattern like tests/**/*.py therefore misses tests/test_ops.py, even though Path.glob includes it when the baseline is built. The file stays in the baseline but is filtered out when changes are restricted to the configured globs, so edits to top-level test files do not trigger a rerun.

This adds a small matcher that also tries the zero-directory variant of **/, and uses it for cache_invalidation_files and cache_invalidation_exclude. Patterns without **/ keep the existing fnmatch behavior. The new test covers both tests/test_ops.py and tests/sub/test_deep.py.
