Improve JSDoc types and add eslint-plugin-jsdoc

Standardized JSDoc type annotations across the codebase, replacing 'Object' with 'object' and refining function signatures for better type safety. Added and configured eslint-plugin-jsdoc for enhanced documentation linting, and updated ESLint settings to include adapters and new JSDoc rules. Updated dependencies to include eslint-plugin-jsdoc and related packages.
