chore: Update typescript-eslint settings

[ho991217]

This pull request updates the ESLint configuration and related code to improve TypeScript support, enforce stricter linting rules, and fix minor issues. The most important changes are grouped below.

ESLint Configuration Improvements:

• Switched from js.configs.recommended to eslint.configs.recommended for base ESLint configuration, ensuring better compatibility with the latest ESLint ecosystem.
• Updated TypeScript configuration to use typescript-eslint parser and stricter rules, including enabling the @typescript-eslint/strict-boolean-expressions rule for enhanced type safety.
• Changed TypeScript project glob pattern from ./packages/*/tsconfig.json to ./packages/**/tsconfig.json for broader coverage.
• Removed the unused eslint-config-prettier dependency from package.json to clean up project dependencies.

Code Quality and Bug Fixes:

• Fixed an asynchronous bug in getConfig by awaiting the pathExists check, ensuring correct config file resolution.
• Added an ESLint directive to suppress the no-unused-vars warning for the abstract action method parameter in Base.ts, improving code clarity for future maintainers.
