Apply ruff's safe autofixes. The changes are mechanical and behaviour-preserving. Issues fixed: - F401: remove unused imports. - F841: drop unused local variables and assignments, including discarded await/return values, unused "except ... as e" bindings, and unused "with ... as name" targets. - F541: remove the f prefix from f-strings that contain no placeholders. - E711: compare against None with "is"/"is not" instead of "=="/"!=". - E712: test truthiness directly instead of comparing to True. - E713: use "x not in y" instead of "not x in y". - E714: use "is not" instead of "not ... is". - E731: convert lambdas bound to a name into def statements. - W291/W293: trim trailing whitespace on touched lines.
