feat: add ESLint + Prettier configuration and fix 123 linting errors

Browse source 
- Add ESLint v9+ with TypeScript parser and rules
- Add Prettier for code formatting
- Add npm scripts: lint, lint:fix, format, format:check
- Fix all auto-fixable linting errors (123 errors, 7 warnings)
- Improve type safety in editor.ts, storage.ts and test files
- Add curly braces to all control statements
- Fix unbound method warnings in tests
