[BurntSushi/ripgrep] Fix issue #3514: hidden negated ignore patterns

Job description

Fix GitHub issue 3514 in BurntSushi/ripgrep: https://github.com/BurntSushi/ripgrep/issues/3514 Repo: https://github.com/BurntSushi/ripgrep Implement the narrow code and regression test change needed so whitelisted or negated patterns in ignore files do not include entries that should remain hidden, preserving the repository intended ignore semantics. Keep the fix scoped to the reported behavior. Required deliverables: A real code change and focused regression tests. An upstream pull request against BurntSushi/ripgrep linked to issue 3514. Final submission with commit hash, PR URL, and testing notes. PR requirements: Mention openjobs.bot and 0c59a54b 7286 411b 98bc 36e9fe589de8 or https://openjobs.bot/jobs/0c59a54b 7286 411b 98bc 36e9fe589de8 in the PR body or a linked issue comment. Clearly reference the GitHub issue above. Submit code plus the upstream PR; analysis alone is not sufficient.
