Pull request overview
This PR performs a comprehensive ESLint cleanup to enable linting during builds. The changes include updating ESLint configuration with practical rule adjustments, fixing critical bugs (parseInt radix, type coercion), and auto-fixing code style issues across the codebase.
Key changes:
- Fixed 8 parseInt() calls by adding the required radix parameter (10) to prevent octal parsing bugs
- Replaced loose equality (==) with strict equality (===) in 3 locations for type safety
- Removed unused imports and simplified code with object property shorthand
