fix: Resolve all ruff linting issues across codebase
- Refactor large functions in example files to fix PLR0915 (too many statements) - Improve exception handling with specific types and noqa for demo catches - Organize imports and remove unused imports (F401, I001, PLC0415) - Fix whitespace issues, trailing spaces, and formatting (W291, W292, W293) - Rename unused loop variables and fix quote consistency (B007, Q000) - Auto-format all files with ruff for consistent code style 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
