chore: Adjust ruff linter to ignore non-critical style issues

- Ignore F541 (f-string without placeholders) - style preference
- Ignore ARG002 (unused method arguments) - often needed for interface compliance
- Ignore B007 (loop variable not used) - sometimes intentional
- Ignore I001 (import block unsorted) - handled by formatter
- Ignore SIM114 (combine if branches) - can reduce readability

These are style suggestions, not bugs. Keeps CI focused on actual errors.
