Pull Request Overview

This PR implements support for languageOptions in the oxlint plugin context API, bringing it closer to ESLint compatibility. This allows plugin rules to access information about how a file was parsed, including source type, ECMAScript version, parser options, and globals.

Key changes:

• Added languageOptions property to the plugin context with sourceType, ecmaVersion, parserOptions, and globals properties
• Created PARSER_OPTIONS and LANGUAGE_OPTIONS singleton objects to efficiently provide language configuration
• Exported LanguageOptions type from the main index for plugin consumers
