Pull Request Overview

This PR adds ESLint compatibility types and updates plugin exports to improve compatibility with both defineConfig() and tseslint.config(). The changes introduce intentionally wide type definitions that serve as a bridge between different ESLint configuration systems.

• Add CompatibleConfig and CompatiblePlugin interface definitions with flexible typing
• Update all plugin packages to use the new compatibility types instead of as const assertions
• Standardize function naming from makeConfig/makeLegacyConfig to toFlatConfig/toLegacyConfig across plugins
