Bug Report: `/*` Pattern Matches Recursively

Bug Report: /* Pattern Matches Recursively

Reproducer: https://github.com/zsperske/codeownersReproducer

The library treats /* patterns as recursive (like /**), but GitHub's CODEOWNERS only matches direct children with /*.

Impact:

• /packages/* matches packages/other/src/file.js (should only match packages/other)
• Causes false positives in ownership audits
• Diverges from GitHub's actual PR reviewer assignment

Evidence:

• Run npm test in the reproducer to see the library incorrectly match nested files
• See this PR where GitHub correctly does NOT assign ownership for nested files under /packages/*

Tested with codeowners@5.1.1

Hello! I generated the reproducer with an LLM so apologies for the slop but I've verified it does reproduce the issue.
