chore: run pyupgrade on codebase

What

Added UP rules to Ruff configuration to enforce modern Python syntax, and ran pyupgrade to upgrade Python syntax to be compatible with Python 3.10+.

Why

Keep the codebase using modern Python syntax and features. Adding the rules to Ruff will prevent old patterns from re-emerging.

How

• Added UP rules to Ruff configuration to enforce modern Python syntax
• Used Ruff's auto-fix to address issues first
• Ran pyupgrade manually to catch any remaining issues
• Fixed an issue with InterpolatedString equality comparison that was affected by the syntax modernization
