fix(oxlint/cli): skip parsing base config again for nested config search by Sysix · Pull Request #20809 · oxc-project/oxc

Sysix · 2026-03-27T17:27:10Z

Added a skip check for the base config to avoid parsing it again. Very useful for JS config or JS plugins, where we need roundtrips to JS integrations.

closes #16356
